$16 for a *very* non-performant material? If this was intended for use in high-detail scenes, not meant for gameplay, one would generally just use a flipbook animation, or looping HD video texture (both of which are higher quality and available for free all over). I love options, but c'mon, that's pretty steep. $5, maybe. And you can loop in materials, using custom HLSL nodes. Also, there are better ways of doing this, all around. Somewhere on the forums, Ryan Brucks (of Epic fame) himself touched on this. I've personally been working on a cool water material (not "material blueprint", thankyouverymuch) and utility functions, and am close to the quality achieved here, sitting at ~180 instructions with everything "turned on". The kicker? It's pure procedural. No textures are needed. So this is cool, no doubt about that. In my humble opinion though, it's not "good". It doesn't run fast, and it's more complicated than it needs to be.
Lee is right - you can use a gradient effect when you vertex paint in your chosen 3d modelling platform (I've done it in max), meaning the wind effect shifts from nothing to maximum along the length of the leaf/branch/whatever.
I'm fairly certain you can vertex paint the bottoms of the foliage and control the movement using vertex colors along with the wind node. I did this in an earlier project and was able to create a scene with grass that moved less and less as it went down until stationary. I created the grass and painted the vertexes black to red (bottom to top) in Maya.
SideFX has announced that Houdini Engine Indie is now available for free (previously it cost $99). Independent game developers and CG artists can now get free Houdini Digital Assets built using Houdini’s procedural node-based workflow into apps like Unity, UE4, Maya and Cinema4D.
This is exciting news for indie developers who want to enhance the procedural features in Unreal Engine 4. Houdini Engine Indie brings amazing power to the table which makes it possible for smaller teams to more easily achieve AAA-quality results.
Houdini Engine Indie is said to work with all of the Houdini Engine plug-ins such as Unity, UE4, Autodesk Maya, Cinema 4D and Autodesk 3DS Max. These plug-ins let game devs load Houdini Digital Assets which can be created in Houdini Indie or downloaded from the Unity Asset Store and the Orbolt 3D Smart Asset store.
Houdini Engine Indie is available at SideFX.com. Note that there is a limit of 3 licenses per studio. There is one condition, though – indie developers must make less than $100K USD per year.
To create custom tools, game devs can use Houdini Indie to create assets in the Houdini interface for use in both Unity and UE4. Houdini Indie is available for $199 USD per year.
