The images show the vray displacement modifier used on a brick wall and im wondering what it is that introduces those bright blotches on the wall. As you can see the windowframe has also got some, so I'm thinking too low render settings (hsphere subdivs) (?)
Anyway, the first imaged attached took over 3 hours to render, and thats just a tiny region render. You can see my settings to the right. Does any have any tips on how to correctly set up the displacement modifier's settings? I've seen some good renderings with the use of displacement but this is abit discouraging.
Thanks.
