So I've got a heart model with the faces ‘growing’ over time. It has a subsurface scattering shader using the new Surface Model node.

It works great, but when the model is still in the growing phase, there are dark spots which I assume are due to the rear holes in the model affecting the subsurface calculations.

I wrote out a point cloud file from the full model, but that didn't help.

Where can I go from this point? Baking lighting / textures or something? Is that even possible with SSS?
