Surface Water Droplets

j_stnk

Hello,

How can I put water drops on surfaces like SimonWm wet products? I have looked at the textures for the body surfaces in one of his products. ok, but i want to make a window pane look rained on. I am very adept with imaging editors so how do I put all the materials together for the surface? Can I do it in Daz or do I need some kind of scripting product to do this? thanks!

For 3delight you'd probably want to create a displacement map, a greyscale image where the lighter colors represent how far the water is above the pane, with grey for zero and white for whatever the maximum is. Then set that as your bump map (or displacement map depending on what gives better results), set the index of refraction to 1.3, set the refraction strength to something other than zero, and turn off "multiply specular through opacity." Adjust "horizontal tiles" and "vertical tiles" if the size or aspect ratio of the drops isn't right. I haven't used iray enough to list the details for it but it's probably similar.

That'll probably require lots of tweaking though to get the right look. You also have to adjust the glossiness and the reflection and specular strength to get it to look like glass, and the right settings seem to depend on the lighting. If there's nothing important behind the glass, you could also just set the diffuse color to be a picture of a wet window pane.

I THINK you can pull it off in 3DL without using displacement. Trying to do so in Iray looks awful.

So, yeah, Displacement is definitely the way to go.

Thanks! actually, yxk03, you answered another question i wanted to know. what are the proper settings for bump maps. i was just taking the color texture and desaturating it appling a slight gaussian blur to even up the darker areas to grey.
