I''m after some utilities to help me tidy up/convert/code my X models. I need to be able to do three things: Convert them internally between several vertex types Calculate various normals (As I''ve noticed my X models don''t contain any normal information) Paint different triangles, different colours when I use the D3DFVF_DIFFUSE vertex format. In an ideal world I''ll be changing these kinds of values and then storing them in my own file format. I''m prepared to start writing my own utilities, but this will save me loads of time if somebody already has something like this available. Any help is much appreciated.
