I find that often shaders intended for Poser come into Carrara with a lot of shine and/or highlights.  This is particularly annoying with skin tones.  There can also be some weird multiplying of the percentage application of bumps, which looks like dirt has spread over the surface.

I generally change highlight colors to black (if one is selected).  Strangely, if there is a percentage highlight it does more good to increase it than decrease it.  I don't understand this - perhaps someone can explain it.

If there is a bump, and it is applied at a high percentage, I cut it back to 5% or less and this generally removes the mottled look of overdriven bump.

Does anyone else have any tips or experience with this problem?

Thanks,

Klebnor
