Huge displacement

[Peter M. Gruhn]

I have a downtown area. Roughly 4000' on a side. I'm trying to model the tree canopy by displacing a plane. The map is good enough. It works fine on small test models. But at actual size there is nothing. It looks flat.

 

The best reason I can figure out is that MR displacement is locked to no more than a few inches.

 

I've been working with parameters in Renderer: Shadows & Displacement; and in Special Purpose Maps: Displacement. Am I missing a set of controls somewhere?

 

This implies "oh, no... you can't use displacement to throw up a mountain range" which strikes me as wrong. So I must be missing something.

 

Clues?

Are you using the "displace" modifier, or putting the displacement map in the material editor and applying the "(WSM) displacement" modifier?

Justin is on the right track... I have used a high density mesh, with displacement modifier and then simply mapped my diffuse, etc... with an alpha to it. worked great for aerials and distant shots...
