Re: landscape object based on grayscale image

I'm actually working on a project like that now. I used a plane with a Displacement Deformer and put the grayscale image in the deformer's Shading tab. You need to have many segments in the plane for the detail to work, and play with the height in the deformer to get it to look realistic. I was making an underwater canyon using bathymetry data; and the client then wanted the walls of the canyon to be jagged, but the information wasn't there in the grayscale image, so I ALSO used a Displacement channel in the material and turned on the subpoly option, and applied it to a polygon selection I made of the canyon walls. I used one of the built in noise options in Cinema as the displacement. So, I ended up using the Displacement Deformer to actually make the terrain, and then a Displacement channel in a material to get finer detail. Using the Displacement deformer allows you to see the terrain before rendering and it's easier to work with that way. If you only use Displacement in a material you'll see only a flat plane until you render, which makes it hard to work with other elements in the scene in relation to the terrain.
