Wet, slimy effect?

[rstjohn1]

Just like the title says, any ideas on how to get this effect. I've played around with phong and Anis textures but I can never really get the effect of slime. I can achieve that wet look, but when animated it gives me a chrome effect.

Any ideas?

try adding a bumpmap-like texture to the spectularity to break up the light bounce.

Yeah I've already done that and it helped out a bit. But it still needs a bit more. I wish I could attach a pic here to show you what it looks like right now...

It's pretty close, but it still has that slight wet plastic kind of look to it. I've played with it quite a bit today and it's alot better. I switched from a Phong texture to a Anistropic and thats working out not to bad. It's getting closer to that slimy slug look that I'm after...

try adding a little of the base color to the highlight . Make sure you're dimming it enough so that it doesn't look like a plastic highlight. Slimy stuff is not that reflective/ Its just got a "sheen " to it.

Yeah I've done that already. ALthough it might be a bit shiney. I did try it with a less shiney sheen to it and it didn't right either. Hmmm, I have a feeling that this is going to take alot of experimentation and fiddeling with. Why can't anything just be instantaneous and easy?!!?

I think , maybe just a guess, there is a "clamp" utility to hook to the specular highlight that will contrain the amount to a mid range . I know some people use some utility when surfacing lizards to get that wet look without getting to the plastic look....there are a million utilities I can't figure out myself ...need to spend an day with the renderign referance book ...just don't have the time..
Good luck , experimentation is how we all get better.

It think he was looking for more of a wet-look than slime its self . But good looking material!
Do you still have your ocean shader?
