Mental Ray Fur Rendering Errors

Hello and thanks for looking!

We are having some fur rendering problems in Mental Ray. As you can see the fur renders great except for the black squares in some of our frames and it results in disco hair.

This is how we have the hair layer set up.
Hair: include all geo and lights. Use background shader layer override (set use background shader settings to 0).

We are using this as our frame buffer:
Date Type: RGBA (Half) 4x16 Bit

We are also rendering it as an OpenEXR

Any help is much appreciated!@@!

I answered your post elsewhere but thought it might be useful in here too:

Autodesk is using (their own) old hair/fur shader they haven't updated in some time it appears.

Look here for a more modern solution: djx Blog p_HairTK
My opinions are always my own...and maybe a friend's, but never my employer's.
