$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.
Most recently we’ve had a chance to learn about the newest release from Act-3D – Lumion 7. Lumion is a real-time architectural visualization software, which features a very simple and understandable interface. Unlike modern game engines, this middleware is created specifically for architects and features a pretty understandable and easy to use interface. To better understand the nature of Lumion, have a look at this trailer.
The newest version of the tool includes a lot of features, including the automatic covering of surfaces with ivy, easy weathering and aging of materials, transparency and translucency, area lights and light strips. You also get an ability to place your model on the map with OpenStreetMap. There’s also a wide variety of trees and plants (172 new items). And you can add character animations, vehicles to the final scene.
Developers also included the new material editor and improved the render engine. It does look very impressive and it’s really easy to grasp. The catch is the price. The software costs €3000. So we don’t really think this would prove useful for small independent companies. There is a free version though, so you can give it a try.
