I have been dorking around with ati’s normalmapper at http://www.ati.com/developer/tools.html and it appears to generate normal maps that I can use with Blender in some form.
Has anybody written a script to generate normal maps automagically, using this or some other tool (ORB, nVidia’s melody?). For example, the typical normal map generation process:
make a low-res and hi-res mesh. Make sure the low-res mesh has texture uv coordinates. The hi-res mesh contains detail geometry.
run generator scripts with some appropriate options
either import the new normal map or make the user re-load the texture
Also, can I do all these steps? I dunno if you can make blender load textures using the python API…
