Hey guys I am wondering if anyone can assist...

I am doing an underwater scene in Maya using Mental Ray with Maya's Physical (water) fog.

I am getting banding in the water environment fog. I have tried everything I can think of in Maya and googled and search but coming up short on how to solve this issue.

The link will hopefully show what I am getting...appreciate any help...tia.
