I want to fake trees as a surface layer rather than adding a population of a squillion tree objects... To make this work for slightly closer distances, I need the tree texture to bump realistically, maybe even spiky texture for firs, but I'm having problems adding displacement effects to a layer. What I'm doing is going to the displacement tab of the surface layer and adding a power fractal to the displacement function, then setting this to what I think would be tree-like bumps, but what I get is only minuscule bumps, a few millimetres high. Can someone suggest what I'm doing wrong?
Another thing I'd like to be able to do is put some snow on my tree objects. Is that possible and if so, what would be the basic outline of the procedure?
Thank you!
