Weird renders with a lot of motion.

Hi.

I'm trying to render out a sequence using motion vector pass. The problem is that my materials get wierd in frames with a lot of motion when motion blur is turned on in the render globals. If I turn it off, it looks fine.

Have a looksie:

As you can see, there is a whole lot of dark spots in the face on the image with a lot of motion. This makes the material's overall brightness much lower in frames with a lot of motion blur, and it looks weird.
As you can see, the teeth also seem to be a lot brighter. This makes me suspect that it has something to do with the light map.

I'm using a mix8layer shader with a couple of mia_material_x, misss_fast_shader_x, and displacement.
