I GOT A SHADOW SPOT PROBLEM.

Here is an image of a necklace and bikini string around the neck area. There are numerous shadow spots.

• there is no AO on the figure or on the lights
• I've tried increasing the IDL samples
• turning off all shadows on all lights,
• turning off the light emitters on the figures/clothing,
• turning off cast shadows on figures/clothing.
• I've tried increasing the environment sphere size,
• i've tried stripping the bbenvsphere of any nodes on the  material and setting diffuse to 1.
• I've tried turning off SSS.
• I've tried stripping the figure down to the most basic nodes(texture only).

I've tried everything to possibly fix this but they won't go away.
