I haven't read the entire thread, but fell in here reading the above post on bump map strentgh in P5...with V3 I've been messing with that setting and usually use .025 as head and neck setting for bump, and about .03 for the body...usually gives pretty good results.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
