Many thanks but no joy. Can't find anything that would change the shadow bias - nothing named as such.

The band of light can be adjusted by altering the shadow bias.  Edit the texture in appearance editor to add wear n tear. You may need to make a colour ID map for this using the uv map as a guide for more precise editing.

Trying to add a fedora (from, I believe, 'Party' accessories) to a CC2 character. Luckily I want him bald but still having problems. If I lower the hat onto the head a shadow correctly appears over the face, but once in place a band of light appears where hat meets forehead - where it should actually be the darkest place. I can only change angle and size of hat - there seems to be no other editable areas - I actually want to add some wear and tear. Any ideas?
