On this page:. A Blueprint Macro Library is a container that holds a collection of Macros or self-contained graphs that can be placed as nodes in other Blueprints. These can be time-savers as they can store commonly used sequences of nodes complete with inputs and outputs for both execution and data transfer. Macros are shared among all graphs that reference them, but they are auto-expanded into graphs as if they were a collapsed node during compiling. This means that Blueprint Macro Libraries do not need to be compiled. However, changes to a Macro are only reflected in graphs that reference that Macro when the Blueprint containing those graphs is recompiled.
Creating a Blueprint Macro Library Blueprint Macro Libraries are stored in packages and can be created through the Content Browser like any other asset. In the Content Browser, click on. Select Blueprints Blueprint Macro Library under Create Advanced Asset from the menu that appears. Choose a Parent Class for your Blueprint Macro Library. Your Blueprint Macro Library will now appear in the Content Browser. Type a name for your Blueprint Macro Library under its icon in the Content Browser.
When your Blueprint Macro Library is first created, or when you make changes to it in the Blueprint Editor, an asterisk will be added to the Blueprint Macro Library's icon in the Content Browser. This indicates that the Blueprint Macro Library is not saved. There are two other methods by which to access the Blueprint Macro Library Creation menu from the Content Browser. Right-click in the Asset View (right-hand) panel of the Content Browser, or on a folder in the Asset Tree (left-hand) panel of the Content Browser. In the menu that appears, select Blueprints Blueprint Macro Library under Create Advanced Asset. The Pick Parent Class window will appear, and from this point the Blueprint Macro Library creation process is the same as if you had used the New Asset button. Blueprint Macros Blueprint Macros, or Macros, are essentially the same as collapsed graphs of nodes.
They have an entry point and exit point designated by tunnel nodes. Each tunnel can have any number of execution or data pins which are visible on the macro node when used in other Blueprints and graphs. Creating Blueprint Macros Blueprint Macros can be created within a Blueprint Class or Level Blueprint, just like Blueprint Functions. They can also be organized into Blueprint Macro Libraries.
To create a Blueprint Macro inside a Blueprint Class, Level Blueprint, or Blueprint Macro Library:. In the My Blueprint tab create a new macro, by clicking on the Add Button on the macros list header. Enter a name for your Blueprint Macro. Your Blueprint Macro will open in a new tab in the Graph tab of the Blueprint Editor. You can also create a Blueprint Macro by Right-clicking in the My Blueprint tab and selecting Macro. Building Blueprint Macros When you first create a Blueprint Macro, a new graph will open containing an Inputs tunnel node and an Outputs tunnel node.
In the Details pane for your Blueprint Macro, you can add input and output execution and data pins. You can also set the Description, Category, and Instance Color of your Blueprint Macro. To change the location of the pin for this parameter on the edge of the node, use the up and down arrows in the expanded Details pane entry. To give your Blueprint Macro some functionality, connect data and execution wires to the pins of your Inputs and Outputs tunnel nodes and create a network between them. This example Blueprint Macro checks if the score that is input into the Macro is greater than the necessary score for winning, and then triggers different output execution flows depending on the result of the comparison.
Note here that the Test and Score pins were flipped using the up and down arrows in the Details pane, to avoid wires crossing in the Blueprint Macro graph. Unlike Functions, Macros can have more than one output execution pin, so you can have execution flow like this where different output execution pins are activated depending on the results of graph logic. Also, you could have a Macro with no execution pins that only manipulates data, as long as the nodes within the Macro are not execution nodes.
Using Macros stored in Blueprint Macro Libraries Storing Macros in a Blueprint Macro Library makes them accessible to Blueprint Classes and Level Blueprints throughout your project. There are several ways to add a Macro node to another Blueprint graph.
Like Function nodes and Custom Event Call nodes, it is possible to add multiple copies of Macro nodes throughout the graphs in your Blueprint. To add a Macro, Right-click in the graph and select the Macro in the context menu that appears. You can also drag and drop off the pin of another node, and the Macro will appear in the context menu if it has a parameter pin of the corresponding variable type and flow direction.
Pricing for software is all about numbers: how many we can sell at a given price, versus what it costs to maintain. Of course you're also promising 5% of your gross revenue to Epic - this is where they make their money perhaps, but the numbers for UE4 are obviously larger than for any given plugin.I appreciate the reasoning behind it, but it's ultimately out of a lot of people's price ranges I would imagine. You're providing some very cool functionality, but you are valuing it at a price greater than that of the toolset on which it depends. I would suggest releasing a stripped down version with a license instead of a subscription. $100, gives you basic access but less customization or something.
If people want to upgrade to the full version they can. I dunno, but all in all it's just hard for me to justify the price for something that would only be a minor portion of my work. No offense meant, but you'll probably get many more sales if it were half the price.

Comparing this with other similar plugins such as the UE4 SpeedTree subscription, it is pretty much identical in cost and increased productivity, and they both have a very similar licence (sub runs out, you keep your work but can't modify the parameters anymore). I do understand the point you are trying to make but I personally have no issues with the subscription price as it stands. I have not tried it yet, but it does look really cool and plan on giving it a try soon!

I have not tried it yet, but it does look really cool and plan on giving it a try soon! I would actually argue that this kind of business model hurts them. For example, it's not like I really need a monthly subscription for sky generation. That's definitely a polish pass kind of thing. In that case, I'm going to probably sub for one month near the end of my project, set it up, and then unsub. Which, if that is the intention, then that is great.
That's a really great value. $25 for a month to set up a dynamic cloud system is immensely valuable, but I also feel unfair to the dev. I'd rather pay more upfront for one time to just have perpetual access with maybe one or two free updates. I guess all in all you are right though.

One thing I'd say is totally missing from vanilla Unreal that probably should be in there is a really nice skybox editor. One that allows you to easily create realistic skyboxes with volumetric clouds, proper dynamic lighting, and day/night cycles. I realize making skyboxes that do all this stuff isn't really all that hard, but it's far more involved than I think it should be.
While it's not available on the marketplace, I've been using middleware to provide those features. It's a great tool ( though not without it's faults) that gets better every day. It's definitely got a few faults and some strange nuances ( because it requires engine changes that modify Unreal's stock rendering thread), but overall it's pretty great and is an excellent trade-off in terms of visual quality versus time spent developing. Well, trueSKY has weather effects as well ( you can do rain, snow, lightning/thunder pretty easily out of the box, as well as day/night cycles), but it definitely doesn't really do 'seasons'. Though you could probably create a long enough trueSKY timeline that might get a close approximation. I have not actually used Orbit ( first time I've heard of it), but from what I can tell, it's main advantages over trueSKY would be the price and the fact that it does not appear to require underlying engine code changes ( like trueSKY does).
That alone probably makes it more attractive for the novice/indie developer. I'll be the first to admit that the core rendering changes made by trueSKY make working with UE4 slightly more difficult than it needs to be, and it is occasionally buggy and produces weird rendering errors. For what it's worth, trueSKY currently supports more platforms ( like XB1/PS4/Linux and soon OSX), while Orbit seems to only support Windows at the moment. Worth considering. Orbit's weather system is definitely better than trueSKY's.
The fact that rain/snow automatically respect interior culling, and that snow can accumulate on surfaces, as well as the footstep effects through snow. That's pretty baller and is stuff that trueSKY does not currently implement. Honestly, from the outside there don't seem to be any (or many?). While there are some assets that look like they are required for a decent Unity experience, that doesn't seem to be the case for UE4. Whether that is because the Unity marketplace is more mature and there is a lot more available or because the tools shipping with UE4 are decent enough and don't need third party assets as much. I don't know. Networking, navigation/pathfinding/navmeshes, Blueprint, LoD generation, postprocessing are things that I'd be tempted to go for third party assets for in Unity that ship with UE4, 'batteries included' style.
So on the UE4 side assets seem to be more 'nice to have' than 'must have' to me. There are less prop-like assets though, and the variety in general is still lacking. That is changing fast, though.
Tutorial Initial Configuration If you haven’t already, please see for information on how to install, build and run the plugin in Unreal Engine 4. Whether you have installed trueSKY via the Git Repo or via the binary installer, start by creating and opening a new project. When you first open the scene you will probably see the default Sky and Fog folder in the World Outliner. If so, then it is important to remove the contents of this folder (this may require deleting them individually and not just deleting the folder itself), as the default Fog and Sky sphere can cause issues with trueSKY. After doing this, you should see the default atmospherics disappear, leaving a black sky. Now we can insert a trueSKY Sequence Actor. To do so, click Window - Add Sequence to Scene.
Find the TrueSkySequenceActor in the World Outliner, and in the Details Panel, click on Active Sequence. If there are no existing trueSKY sequences to load, we can create a new one by clicking the Create New Asset option.
Name this whatever you wish and find a location in which to save it. Once done, it will be automatically assigned to the TrueSkySequenceActor. You can change the sequence currently in use at any time by clicking on the Active Sequence option. Adding Clouds The sky in your scene should now appear blue, but will lack clouds or anything interesting. To liven up the scene, find your newly created sequence asset in the Content Browser and double click it.
This will load the trueSKY Sequencer. If you haven’t already, input your license key into the sequencer to allow full access. For now however we will just add some basic clouds to the scene. To do this, right click in the 3D Clouds section of the timeline and click “New cloud keyframe”. Select the keyframe and try experimenting with the values. You can also use the Presets on the left hand side of the sequencer to select predefined arrangements.
Be sure to set the Wind Speed value to something greater than 0, if you wish to see the clouds move (once time is being progressed). To further enhance the scene, you can also add a keyframe for 2D clouds, by right clicking on the 2D Clouds area and creating a keyframe in the same manner as before. In this example I have set the Wind Speed to 1, raised the cloudbase to 5.0 and increased cloudiness by to 0.6.
I have also added a 2D cloud keyframe with default settings. Progressing Time Though we can now see clouds, you will notice that they aren’t moving, even if the Wind Speed has been increased above 0.
To get some movement in the scene we can use the Blueprint system to drive trueSKY. To do this we will want to progress the trueSKY time. Open up the level blueprint and create an Event Tick event. Next create a float variable to store the current time, then connect the Event Tick event to a Setter for this variable. For framerate independence, we should use Delta Time to progress the trueSKY time. To do this, create a Getter for the Time variable and then a “Float + Float” function and a “Float / Float” function.
Connect the Delta Seconds pin from the Event Tick event to the divide function, then connect the output from this to the addition function. Next connect the Time Getter to the other input pin of the addition function, and then connect the ouput pin of the addition function to the Time Setter.
Lastly find the trueSKY Set Time function and connect the Time Setter to this, and pass the Time variable output pin to the Set Time function’s float input pin. If you press Play/Simulate now you will see the clouds move and the day turn to night very quickly.

This is because we are not scaling the raw Delta Time input just yet, so every real time second is progressing trueSKY by one whole day. It is unlikely that you would want the days to move so quickly, so try replacing the second argument in the division function that is receiving the Delta Time input, with a more suitable value. For example, a value of 60 will equate one trueSKY day to 60 seconds, a value of 3600 would equal an hour and a value of 86400 (60 x 60 x 24) would simulate a real day. In this example I am using 600, so a full day will pass in ten minutes. You may find that you need to change the Wind Speed variable to suit the rate at which you are changing time. Additionally, if you want the scene to start at a specific time, try changing the default value of the Time float variable (where 0.0 is the start of the first day, 0.5 is noon on the first day and 1.0 is the start of the second day).
Implementing Lighting Now that time is moving and the clouds are behaving properly, the next element of trueSKY to configure is the lighting. In trueSKY you can drive both the Sun and the Moon using the Blueprint system.
By default your scene should already have a directional light present. Ensure that its Mobility (Details Panel - Transform) is set to Movable.
Open up the level blueprint and create a reference to the directional light. Now connect it to the UpdateLight function. You can also apply a multiplier to each to scale the brightness (in this example I have left the sun at 1.0 but doubled the moon’s brightness). Ambient Light with TrueSkyLight The default Unreal Engine Skylight is not dynamic. To get the most out of trueSKY it is advisable to replace this with a TrueSkyLight (Modes - All Classes). Do not manually capture the cubemap when using this Skylight: it works automatically. You can adjust the update frequency (default 4 means every four frames the TrueSkyLight is updated), and the Diffuse and Specular brightness - it’s recommended not to change these dynamically, but choose in advance the values that work best.
The Blend property controls how smoothly (and thus, slowly) the light changes over time. It’s also worth rembering to set the Render Textures for Loss, Inscatter and Cloud Visibility (these won’t be much use here, but are important when rendering transparent materials alongside trueSKY). With that your scene is now fully configured and should be showing moving clouds and correct lighting.
Of course this is a very basic scene, so to learn more and get the most out of trueSKY for Unreal, please see the further information section below. Cloud Shadows To enable cloud shadows, connect the render texture “CloudShadowRT” to the “Cloud Shadow” slot of the trueSKY Sequence Actor.
Assign the material function MLightFunction to the “Light Function Material” slot of your Directional Light. You will need to run or simulate to see cloud shadows moving correctly. Rain Masking To prevent rain from falling in covered areas, create a SceneCapture2D actor, and give it a texture target that’s contains only a red channel (e.g. RainDepthRT from the trueSKY content). Make the Capture Source “SceneDepth in R”. You don’t need to enable “Capture Every Frame” unless you expect the geometry to change. Rotate the Scene Capture 2D to face upwards.
On the trueSKY Sequence Actor, assign the Scene Capture 2D actor to the Rain Mask SceneCapture property. Now, rain will only appear where there is no cover above the Scene Capture actor. Further Information. Next: For more information see.
TrueSKY for Unreal Engine 4 Getting started. Register your username at. You’ll find your licence.
After evaluating, to get an indie licence, you can buy or subscribe. For all other licences, write to. Installing the Plugin For binary installations of Unreal Engine, binary trueSKY plugin installers are available from. For other versions, or if you have a version of Unreal Engine built from source, you will need to build the plugin. Important The stock binary version of Unreal does not deploy trueSKY files when packaging a project. You will see a black sky unless you deploy these files.
See for instructions. Running the Plugin. Run UE4, either standalone or with the debugger. TrueSkyPlugin loads TrueSkyUIMD.dll and UE4PluginRenderInterfaceMT.dll from UE4 Engine Plugins TrueSkyPlugin Binaries Win64. When you run the UE4 editor, the trueSKY plugin should be enabled by default. If not, open up the Plugin Configurator for Unreal Engine (from the menu bar: Edit-Plugins).
Chain link fencing can be tricky to install on a hill. The webbing between the posts was generally designed for a flat surface, and creates odd angles at the ends when erected on a graded slope. The secret lies in making a bias cut at the end of the post, which gives the chain link an even appearance.
Chain link fence installation is a fairly. How to Bias-cut on a Chain Link Fence. Building a Fence on a Slope; How to Estimate Chain Link Fence. Install the line posts vertically at regular intervals along the course of the slope on the intended fence line. The posts should be located and installed just the same as on flat ground. Depending on the size of the fence, you may need to use a post hole auger to dig holes for the posts. Mar 28, 2015 Learning how to build a fence on a slope is something you cannot do on your own. How to install chain link fence on a slope. A chain link fence with slats was chosen because it is easier to see the angle of the chain link installed on a slope. The red circles indicate where the chain link has been cut to accommodate the bias (bias cut).
In the plugin configuration window and type “trueSKY” into the search box to find the plugin; check the “Enabled” box to enable it. If you had to change the “Enabled” setting from disabled to enabled (or vice versa), you’ll need to restart the editor for the change to take effect, as with all editor plugin changes. Adding trueSKY to Your Level Precautions. Most UE4 maps contain a Sky Sphere and Atmospheric Fog:.
Delete the Sky Sphere object – The Sky Sphere will actively obscure aspects of the trueSKY rendering system, as it’s basically a giant ball of geometry with a texture applied; you’ll want to delete this object. Delete any Atmospheric Fog object – Having Atmospheric Fog will not break anything, per se, but given that trueSKY provides a more detailed and physically-accurate atmospheric rendering solution, it can serve as a complete replacement. Adding the trueSKY Sequence Actor The trueSKY Sequence Actor is the primary way to access and interact with the trueSKY renderer and its rendered sky sequence within Unreal Engine 4. You can add this actor from the standard “Place” sidebar in the editor, choosing “All Classes”, typing “trueSKY”, and choosing the “True Sky Sequence Actor” to drag into your scene, or you can use this handy little shortcut:. From the menu bar, use: “Window-Add Sequence to Scene”. This adds the default True Sky Sequence Actor to the current level at the map’s origin (though its location doesn’t matter – its rotation, however, does). Once you have the True Sky Sequence Actor in your scene, choose it from “World Outliner” window.
Then, to customize it, open up the “Details” window/sidebar; set the reference to an existing TrueSky Sequence Asset in the “Active Sequence” dropdown. By default, there are two sample sequences you can instantly check and see the results for yourself:. TrueSkySequenceCumulus – A prototypical cumulus cloud pattern (with a 3D and 2D cloud keyframe for example purposes). TrueSkySequenceStratus – A prototypical stratus cloud system; i.e.
There’s a rain/snow comin’ (with a 3D and 2D cloud keyframe for example purposes). Creating New Sky Sequences To create a new TrueSkySequence asset, go to the “Content Browser” window.
Press “New Asset” button (or do a right mouse click inside the window) to open an asset selection window. Choose “Miscellaneous / trueSKY Sequence Asset”. A new asset will be created. Now you can rename/save/delete it. In the World Outliner, select your trueSKY sequence actor, and in the Details panel, set its Active Sequence to be the newly created asset: To edit the TrueSkySequence asset just double-click on it: This will open up the True Sky Sequence Editor: Creating and Configuring a Sky Sequence. Enter your licence key in the Sequencer Window. This enables the window’s editing functions.
You can see changes to the properties (e.g. “preview”) only if the edited asset is also assigned to the level’s TrueSkySequenceActor. The trueSky plugin renderer uses only the asset which is referenced from that actor. If you are editing some other asset (which is not assigned to the TrueSky actor of the current level) then you won’t see any visualization of it.
You can edit any number of TrueSkySequence assets at once. However, only that which is also assigned to the active TrueSkySequenceActor is visible in the editor rendering window. To add clouds, double-click the trueSKY Sequence Asset and right-click on the timeline to add cloud keyframes. For real-time ambient lighting and reflections, replace the default SkyLight Actor with the TrueSkyLight (found in Modes - All Classes).
Simply drag it into the scene to use. Multiple Sequence Actors and Transitions You can have any number of trueSKY Sequence Actors in your level, all with different Sequence Assets assigned. In the Editor, check the Actor’s property “Active in Editor” to see its weather state in the 3D view. In-game, the active Actor is determined by bounds. By default, a Sequence Actor is unbounded – it is always active. You can create bounding by adding a Box Collision component to the Actor. When this is done, the Actor will have limited bounds, and only affect the weather when the player is within the bounding box.
Unity
You should have at most one unbounded trueSKY Sequence Actor in your level: this will apply when the player is not in the bounds of any other Sequence Actor. To allow a smooth transition between weather states, you should adjust the Mode property of the Sky and Cloud Layers in all the Sequence Assets to allow a gradual transition between the different weather states. If you’re using real-time transition (this is simplest), you can adjust the Interval in seconds (default 10.0) to determine how quickly the change takes place. Otherwise, use the Interval in days. Performance Use the Blueprint function GetProfilingText to get GPU and CPU timing numbers for trueSKY as a tree. TrueSKY performance is highly dependent on your choice of settings. Once you have good settings for a given target hardware setup, performance will be consistent - i.e.
There won’t be spikes or hitches. For PC, you may want to make some of these settings controllable for the end user.
For console hardware, it is usually best to choose the settings based on your target GPU time for skies, then lock them down. Sequence Actor Settings. Max Resolution: This is the cubemap resolution that we render clouds into. A lower value will be faster to render. Too low, and clouds may appear blocky. A good value tends to be:.
512 – Likely the optimal resolution for most use-cases; it tends to be the best mix of memory consumption/performance and rendering sharpness/clarity for general use. 256 – This is a decent resolution that is faster and uses less memory than 512, but is not quite as sharp and clear. Amortization: This is a measure of how cloud rendering is spread across multiple frames.
Thomas The Tank Engine True Form
A value of 1 means all pixels are rendered every frame. Further Information. Next: For more information see.
