Bump Mapping
Bump Mapping
How do I make bump map Textures. Is there a way to do it in gimp or do I have to make them by hand.

You can do it in gimp. or in 0.4.8 when it comes out if it has the feature.
look at that. from a scaled and smoothed desert stone to the chunky stone you might see in reality

The colors in a normal map refer to the relative change in elevation from one pixel to the next.
The pixel's green channel (as in RGB) is used for the Y axis, red for the X axis, and blue for the Z axis (depth). This allows a normalmap to store three independent vectors for each pixel. This is also why they have to be PNG or some other lossless format - the channels must not blur/blend together, as would happen with a JPG image.
