Ah yes, now I remember us talking about the height map. Basically any sort of arbitrary transformation of UV coordinates to another, better set of UV coordinates can be encoded in an image. Actually the possibility exists to use not gray scale, but red, green, and blue to represent X, Y, and Z. Or other things are possible, like a straightened UV map encoded as red/green, so I could also rely on a given U coordinate to be straight up and down, thus able to produce a straight seam on the back of the leg.

I don't think super high resolution is needed, since interpolation between sampled points is likely to produce very little error. So i bet a 512 by 512 would be good enough. But experiments will need to be done to confirm that.

I don't need it any particular time. When you feel like it.
