			A few other things that might be important:

			The name for the texture in the hi and lo poly model must be different.

			Remove the uvmap for the hipoly model?

Use the built-in renderbump command in the Doom3 console (or in DoomEdit) to generate a normalmap for your low-poly models. These are some barebone notes to prevent myself from forgetting how this works, so beware ;)

* Create your mesh - make it as high-poly as you like
* Create your low-poly mesh and try to meet the shape of the high-poly model as far as possible.
* Create a U/V map for your low-poly mesh and take care that no face is sharing the same texture space.
* Place your two meshes such that they are sharing the same 3D space - the high-poly model should "envelope" the low-poly one.
* Hit "Apply Scale and Rotation" (Ctrl-A)
* Export your two meshes to ASE (using goofos ASE exporter script) to '''test.ase''' and '''test_hi.ase'''
** Enable these options for the low-poly mesh: '''Face UV''', '''Selection Only''' and '''UV Image as Material'''. Disable the other ones.
** Disable all options when exporting your high-poly mesh: just tick the '''Selection Only''' option.
* Create a shader definition containing the renderbump keyword:
textures/darkmod/test
{
renderbump -size 1024 1024 -aa 2 -trace 0.5 -colorMap textures/darkmod/test_local.tga models/test_hi.ase
}
* Change the material information (the *BITMAP one) for your low-poly mesh to point at this valid shader:
//base/textures/darkmod/test
* Run DEdit or Doom3 and type this in the console:
renderbump models/test.ase
* This will take some time (up to several ten minutes) and will create the '''textures/darkmod/test_local.tga'''.
* Check your normalmap if it looks choppy or something. You might want to tune the -trace parameter or manually edit the normalmap.
