This is my first post on the forum.
Couldnt find anything related to this problem.
Im using a character with Sub surface scattering material.
Inside is a skeleton, which also uses the same vertex motion blur setting so the entire body acts as one when it comes to motion blur.
Now when there is a hard backlight in a certain scene, the motion blur messes up in the parts where the hand is directly in front of the light.
When there is geometry between the light and the character, like the other character with the same materials, or the wall next to it, this doesnt happen.
The geometry that does show, is not the skeleton, nor the hand geo.
The actual skeleton is much thinner, and the hand geo is obviously thicker that what it showing.
I had no luck changing the amount of samples, as far is can tell anyway
Any help would be much appreciated, thank you
