$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.
! Today Epic Games and Wellcome Trust have launched a new competition Developing Beyond. It will last for a year and will give you a chance to get a piece of the hefty $500,000 pie. [UPD: Unreal Dev Grants still going. Sorry for the mistake.]
To take part in the competition you need to submit compelling, immersive, and highly entertaining game ideas based on the theme of “Transformations”. It’s available only from the developers from Europe. There’s also a UE4-restriction. Plus games have to be made for PC. The finalists will be announced by February 20, 2017.
If you’re lucky enough to get into semi-finals, your studio will receive $15,000. With this money, the idea should be developed into a prototype, which will be presented to the jury at Develop: Brighton. There will be three finalists, each to be awarded $60,000 to continue work. They will be tasked with building the Minimum Viable Product. The winner will get $150,000 in January 2018! The second and third place will get $50,000 and $30,000, accordingly.
The bad thing is that the deadline for applications is February 10. Better start working on those amazing game ideas now.
