I made an edge map using the pointiness node and some musgrave noise texture.
When I try to bake this "edge map" (baking using "emit" option), however, the thin edges of the object show stretching in the baked image, unlike what the edge map looks like in rendered mode (fine dots of noise).
My screen shot shows the rendered result on the left and the baked result on the right. Notice the stretching at the edges of the UVs.
Thanks for any help in understanding this!
