Remember though that when using Raytrace Objects, your displacement gets rendered as a bump map.

What do you exactly mean, Oshyan. What's the difference between bump map and displacement? Or am I a bit foggy in the head?

Bump uses greyscale values to mimic 3d appearances on surfaces - so the bricks may look 3d from a distance, but no actual geometry is added - you'll see that edges of the house at the corners will not look bumpy at all.  Displacement takes the greyscale values and actually adds geometry.  This makes displacement more realistic, but much longer to render.

I got used to hard 'coding' the displacements when I model something. Displacement works weirdly when something gets scaled up or down.

Thanks, Eoin. Now I understand why I saw some straight sides in my tree trunks, but displaced surface...
