Refractions in Post anybody ?

Hello 2 all

I have a scene which has some bubbles rising towards the surface.

Now the bubbles I have put into there won layer with a black backdrop.

the reason being, is that I have an HDRI image as a mental ray image based lighting which uses final gather.

This image alone makes my bubbles look very very bright and unconvincing.

But they look great on a black backdrop, using maya software
via (layer overide)

Now I also have a shark that swims past and hits the camera,
Now to get the refractions in the hubbles of the fish that swims past I just turned the sharks primary visibilty to off but still having it visible in reflections and refractions.

BUT beacuse the shark using on 3 lights for lighting and the other light source is final gather ( which makes my bubbles look like bright light bulbs)

this wont do !!

My shark uses Mental ray Map files so they won't render in maya software.

How can I get the refractions of the shark as it swims by in the bubbles with out the brightness of the HDRI image ? taking into account that I need it to like the fish.

AHHHH this is really confusing can anybody help ??

Thanks

fix your bubble material that you are rendering in MR so that it doesn't take so much light from the HDRI image.

Hi

I have gone into the Light relationships editor and turned off the influence of the hdri on my bubble completely and it still shows up.

How would I turned down the influence ?

thanks

adjust the properties of the material such that it doesn't take as much light frmo the HDRI OR go and edit you hdri and lower the intensity (probably a multiplier somewhere to adjust it's intensity)
