Puzzle (see shared gDrive directory):
"bioluminescence_dyn_." — 3D fluid effect in one scene renders with Mental Ray just fine
"caustics_." — caustics effect in a separate scene renders with Mental Ray just fine
"underwater_." — When I try to import the 3D fluid effect into the caustics scene, suddenly, the 3D fluid will only render with Maya Software, but caustics continue showing up in Mental Ray render
"waterunder_." — If I try to do it the other way around (importing the caustics into the 3D fluid scene), the caustics stop rendering properly altogether
How do I get both of these into the same scene so that they still render properly with Mental Ray?
