Will someone please help me???!

Why does this 'dots' show on the NECK in some my renders?

Im using PoserPro 2014 and default lights with Gamma.

i've noticed it appears in some lights and materials I use!

Please help me to fix this!

No idea, but do they correlate to the mesh? The spots are pretty uniformly arranged in a grid.

Looks like your ray traced shadows Shadow Min Bias is set too low. With your shadow enabled light selected open the Properties tab of the Parameter Dials palette. Raise your Shadow Min Bias value to 0.200. Do the artifacts lessen or go away?

Does it happen with Gamma turned off?

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.

I go with what  @EldritchCellar has said.  When I have extreme difficulty in getting rid of dark patches, I usually set Shadow Blur Radius as high as possible ( 8.0 ), and Shadow Minimum Bias as low as possible ( 0.000001).

Yes... both ways. With and without gamma :(

Hi guys! I tried increasing the Shadow Min Bias - same results. !! :( 

I was using the Mario character mat - Then I changed the mat and did not happens! 

This one is the Severin MAT and Poser default lights!. Looks like the problem is on MArio's mat!

OK - pity the first MAT shader didn't work out in your scene. Glad you got it all fixed now.  Render looks cool.
