Played with the maps used for my last post some more.
This time both as greyscale images. Bump on the object and displacement on the terrain.
The object was done in 'Wings 3D' and is not UV-mapped. Image maps were applied in
'Object UV(if available)' mode and in world space.
The background is just something to get rid of the gray default scene.
Tested various versions of the object originally, here is one of them.
