Yep I read some tutorials and get to it that i have to group faces. Now it works properly. Thanks a lot for reply!

Hey guys,

I'm totally beginner in a field of Sketchup and VfSU so don't be mad if I'm going to write something seriously stupid in some following phrases Trying to help a friend of mine.

My problem is: I've downloaded Sketchup, regular edition 8, and the newest VfSU for it. I've also downloaded some vismats, which you can find on internet (the one which is a collection of 140 materials). There is one particular which I'm interested in - Sea water material. When I'm just making a normal rectangular prism and applying that material to it, then it renders fine (just rectangular prism in model). But when I'll add some cube with material of leather (also from that collection) it gets really messy (there is no displacement in sea water material, and it should be and even the color of sea water is kinda messed up), but leather material renders fine. That's the first problem. Another one is: in a more complicated model, when applying sea water to the shape of bay, it doesn't work. Again no displacement and color little messed up. Even if I'll try just to put some texture on it (instead of sea water material) it doesn't work properly. I'm really out of any more ideas. So I would appreciate even a little hint. Kinda desperate about that. Oh visopt is set default. Probably I'm doing something wrong, but what is it?

Cheers!
