I am creating a desert scene and have come up with this so far
I have a bump map currently on the surface. When I assign a displacment map I made to the surface the surface gets all wierd and distorted. Please help.:sad:

You need to be aware that bump maps works with the light itself. No light no bumps, whereas displacement map actually modify the geometry. You need to modify the alpha gain if you are using an image for your displacement.

Map the "displacement" texture temporarily to a material's channel, such as Color, which displays the results in the view (with Hardware Texturing turned on).

Thx for the help :thumbsup:

I have also heard about normal maps. What exatly are they and how can I apply them?
(note: I am a texture and rendering noob)

Normal maps are generally used in the game industry where you use a high resolution mesh detail and transfer its detail to a low resolution mesh via their normals. You bake the detail into a texture through the normals. The difference with the bump maps which is grayscale map is that the normal mapping is composed of the three rgb values.
