And I figured out lighting a little better, and in the process ran into a nasty "bug/feature" in mesa triggered by our large coordinates (which necessitates a MODELVIEW matrix with a very very small determinant, and then things inside mesa give up when trying to invert it). I fixed the issue by scaling "w" of the homogeneous coordinates rather than using glScale, which scales x, y and z. http://www2.eng.cam.ac.uk/~pcjc2/geda/pcb+gl_3d/pcb+gl_3d_packages_mockup2.png The code which rendered this is in my "local_customisation" branch. It will pick out and 3D-abuse any ACY400 footprints it finds (placed by gsch2pcb ONLY) on the board. (gsch2pcb leaves a tell-tale description which lets me see what footprint was requested).
