Anyone know of a script to export uv normal maps from a 3dmesh in tangent space?
I’m working on a game with a pseudo celshader which creates shadows based off the curvature of a model. Due to the polycount restriction of games I think it would be better to apply a highres normalmap for the lowpoly model, so that the shader can apply smooth shadows similar to an anime.
I’ve been trying to use Dra[en]gine’s Normal Map generator which has a python script which exports some strange format from blender but the program is buggy and gives screwy results. I don’t really want to go through the trouble of exporting to 3ds and using Nvidia Melody as I don’t use 3ds and futhermore I have to run Melody through cedega and it doesn’t export the tga’s for some reason.
Anyone have any ideas of how to export these?
