Actually he is painting on vertex colors - I'm just being a technicality snob. Virtuosic called it a vertex shader (i.e. vertex program in the graphics pipeline), where it's actually a complex pixel shader that makes creative use of vertex colors.
Pretty neat :) Probably way too expensive to use massively in production, but you could possibly optimize it down and use it in key areas. One gripe - it's not vertex shader. It's a pixel shader that uses custom vertex colors :P
Ah, thanks for clearing that up, thought the resolution on that plane seemed a bit high for vertex painting. Blastradius: Most all major 3d suites allow you to paint vertex colors into the model, you can even export them in your ASE file and use the color information in the material editor.
This is actually a double post, the original post was at the thread MoP was talking about. That thread helped me out so i thought i'd chronicle my R&D in that thread as well, mainly because i had to give those guys credit for helping me out. However this thread is my personal documentation not only for myself but for you…
Bah, sorry guys. ya it's a material for vertex painting. Crazy Fingers - The resolution on those planes was 4x4. it had 16 verts. The shader is cool because it uses the vertex paint and adds in a noise map to the vertex transition. That way you can paint on low detail meshes and still get a really interesting noisy…
why not post a shot of the actual shader? That would be nice to see. Haven't messed with in game vertex painting in UT3 much yet, might have to get into that. Anyway, cool post, but again would be far more interesting if the actual material setup were posted.
