Stremik Posted August 10, 2004 Share Posted August 10, 2004 Im trying to create an shader in VOPs that would simulate an underwater look. With caustics etc. Naturally, I thought that I would have to use an Volume or Enviroment shader for this and there is such thing in Houdini. "RSL Volume" shader it is. But it's undocumented! Can anyone explain or give an example maybe on how to use it? Or even better, does anyone have an Volume shader in .vfl format, so I can take a look at it? Thank you! Vladimir.

Stremik Posted August 11, 2004 Author Share Posted August 11, 2004 Maybe at least some PRMan "Volume" shader? Anybody? Vladimir Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted August 11, 2004 Share Posted August 11, 2004 Hi, Stremik. You can write a surface shader for caustics and a fog shader for the "depth" like look. I have an example which I made for myself. It's a COP caustics generator. You can rewrite my COP to your surf shader. Principles are similar - noise (for example periodic noise) with jitter. Scene is here caustics.rar Hope this help Quote Link to comment Share on other sites More sharing options...
