Normal Mapping?

[prometheus]

I do not see in the documentation how to enable normal mapping.

The documentation for normal mapping will be added soon, but the process is pretty easy. Create your normal map by any means. I like using the NVidia normal map plugin for Photoshop, which you can download from their website:

http://developer.nvidia.com/object/photoshop_dds_plugins.html

Using the plugin you can either convert a greyscale bump map to a normal map, or even just use the model's diffuse map. After you have created the normal map, add a Normal Bump map type to the bump channel of your material. Then add the normal map to the Normal Bump map type.
