$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.

Photogrammetry: Macro-environment in CRYENGINE

CG-artist Simon Majar shared some assets for an exclusive photogrammetry demo for CRYENGINE. A great opportunity to have a look at how this 3D scanning technology works.

The demo assets are absolutely free and available for download at CRYENGINE forums. The files feature a very detailed look at the scanned piece of environment and give some insights on the way the whole process works. Te detailed description of the scan is available in Simon’s official blog.

I used Agisoft Photoscan to make the model and textures. Medium settings, with my 8gb of ram, not possible to generate a really dense point cloud. I’ll try later with a more powerfull computer. From that model I generated two 8192px textures. The rest is easy, export and integrate to the CRYENGINE. What I didn’t do, and should have been done, is delete every lighting information in the textures. I’m still working on a proper way to do it. It’s quite complicated, and the best way to do it is capturing the environment to have an HDRI. But I don’t have the equipment yet, just a middle class camera.

As a result the demo has baked lighting. In the video the camera is actually not moving. Instead the level itself is turning around.

[…] haven’t had the pleasure to use photogrammetry to an extent to review it, but based on the work I have seen trough personal projects and in game […]
