Having problems with Arnold's Curvature map and scale


#1

Scaling this model I’m working on does not scale the Curvature map applied to it accordingly. Or so it seems. I can’t quite wrap my mind around it. The curves, nor anything for that matter, changes except the scale of the entire model. The bitmaps don’t scale, the UVs don’t scale, only the map changes. Any ideas?
