$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.
Renderpeople has recently released a ready-to-use animated 3D People freebie called Sophia which can be used commercially and downloaded without registration. Let’s take a look at the model.
Renderpeople is a studio that provides lifelike and easy-to-use 3D People for different renders. The project offers a range of free products, as well as some paid ones for you to make your works stand out.
Finally, here they are… the newest addition to our 3D People line-up: the Animated People! Just import them into your 3D scene and you are good to go. Available as 3ds Max, Cinema 4D, Maya, and FBX.
You can learn more about the project and get the latest free model here.
