For textureCoordinates do: > tc1 = tc1_original * w > tc2 = tc2_original * w > tc3 = 0 > tc4 = w > > where w is any sensibly arbitrary number (say Math.PI) Hmm that sounds like a good idea thanks, at least through Geometry this should actually work out. It will be a bit harder with automatic generations, but I will see what I can think of. I also though of writing an identity texture which simply reflects the texture coordinate and try to see where visually my coordinates are lying. > is indexed, then I would expect the original and modified > cases to produce identical results.
