I have forgotten: the first picture with "ice-water"-effects as attachment, very simple vsl, o.k.:-) I have combined two textures, but the effect ist good! only the rendering times are increasing (bad!);-) bye, servus, Frank Brübach

(matt glass), after that I will manage a special look for "roughness" and "cold-freezing" roughness... I will have a certain look to the examples from the rs folder (vsl or material)... - creating such vsl things and learn with the shader language, for me it's not so easy to handle with the vsl stuff (yes, very amazing!) but the vsl power is damned great, the input/output channels are really wide spread;-) must laugh... yes, If you have some ideas, bring it to the forum :-) I am working forword tomorrow with the vsl shader and bring the next results here... best regards, servus, Frank "ice-shader" made of this: color, transparency, refraction, fresnel, fog, bumpmap/ noise... good evening:-) -----Ursprüngliche Nachricht----- Von: [email protected] Gesendet: 17.04.08 14:10:27 An: [email protected] Betreff: Re: open question for an ice shader cooperation:-) A good start on all shaders is to think what the qualities of the material are (i.e. what makes ice look like ice). The glass-like parts are easy enough, you can pretty much just use a glass shader as a base (with a tweaked color and optical thickness). The harder parts are the surface features and air bubbles inside the ice. The surface features can either be modeled or done with some creative bumpmapping (there's some bump materials in the startup project that fit the bill). The air bubbles are harder though: you can either model them or just cheat and add a high frequency noise to the bump. I'll see if I can give you some pointers once I get home.
