Of course I took antialiasing off, for quick rendering

This is just a guess, going by what the problem appears to be to me. The black areas look like shadows to me. in your e selection for the lights. turn off cast shadows

Umm... the top of the falling paint is higher than the level inside of the bottle. Also, perhaps you should add a little bit of dried paint to the end of the brush on the cap, since it would usually be kept inside the paint bottle... Umm... these are mostly little nitpicks though. For the most part, it looks good. Rosh

Sorry to take so long Maga, (tryin to get some things done at the Challenge Arena" at first Glance I would tend to agree with Boney. Are those colorful lines,Objects,or actual lights? If they are lights ,select diasble cast shadows as bone suggested . you culd also turn shadows off and self shadows off in the materials editor. if they are cyllindres(objects) try turnig off shadows for them too. at least if you do that and if the lines are still there ,we will have eliminated the shadows as the problem. Hope this helps. what I cant understand is why they were gone ,and then came back when you changed the camera angle. Hawkfyr

I will follw your advice, friends. these are actual lights, but what about a tip for having a more realistic look at the enamel drop?

I'd say make it a bit transparent and turn up the specularity. Might look more effective if it was red also. The orange brown is kind of a neutral color. You might also see if you can round the edges off a bit also. I assume they're lattices, so go into the terrain editor and layer the edges out with increasingly dark shades. And the dribble that's coming from the bottle does need to be lowered, and smoothed a bit also. If it was me, I'd make it red, make it a touch transparent, then put a small radial light tinted red inside the bottle, inside the enamel, and see if any glow resulted

Great Idea Bone. You know what else might be cool? Try setting a radial light behind and above the enamel as to cast a glare or reflection into the camera's view. Then... whatever texture you decide to use for the enamel, try using another color or texture in the same hue, to drive the "Specularity"channel. That way the reflected highlights will cast that color. Perhaps a metallic texture. Hawkfyr
