Here's my problem. When I'm using disp. on grass and walls in my window reflection there are black spots. How can I get rid of them?Please help me.

Oh. Resolution is 4000x325.

So there's no solution for this?

[pete242]

are you shure that you don't have displacement in your glass?

[lukx]

yep there's no disp on glass.

Ok at least I got the solution. My wall is box and has UVW Box mapping. Wall was about 25cm thick and my UVW mapping was the same. When I changed UVW to 0.01 width, there are no spots.
