The Wet look

[dnightmare]

I'm trying to make a wet looking Alien with dripping slime.
Anyone know a good way to may a wet surface shader, and a good way to make a dripping slime?

Dripping slime???? how much work you willing to put into this one... thats a tall order.

Wet shader, easy I'm sure there are many ways out there. This is one I often use Layered shader, bottom layer is normal dry alien with what ever you are using for color bump spec etc. Top shader is a transparent blinn, remap the same bump into the top shaders bump, and give it a real tight bright spec hit start with an ecc = .1 spec roll off = 1.5. Adjust to approriate levels. Then do very slight reflection map of your environment in its reflectivity just to get hints of color and reflections (very slight environ cube). This will give it an over all wetness, if you only want it wet like this in certain areas, then you'll have to do more work with alphas.

Whatcolor should I use for the top layer or does it need to be 100% tranparent?

[twedzel]

Top Shader (make sure you are using layered shader not layered texture) should be %100 transparent, if you want it to have a tinge of color then change the spec color. The top Shader is just to give a wet spec, and not any color. If you don't map the bump into it, then it will have a shrink wrap plasticy look.

well, if you get dripping slim.post how you did it.

a cheep and fast way for a wet look is to get a point light that only emits specularity and position constrain it to the camera
