hi everyone. I'm new to the concept of image based lighting...I thought I was getting the hang of it because my stills looked great. the only problem was when I rendered out a sequence of frames with the camera moving, I noticed a lot of flickering and flashing in certain areas, especially where I used displacement. does anyone know how to get rid of the flickering? let me know if anyone needs more info.

Version of Maya and Mental Ray?

Sounds like Final Gather flickering...

Im using maya 8.5. Do I need to turn off final gather while using that type of lighting?

Not necessarily I'd do a test and see if it is FG causing the flickering.

If it is then there's some options you can tweak to reduce/remove this. Check the documentation / web for some good guides on it (just make sure what you're reading is relevant to your version of MR since there was a major change around v3.6 to FG).

If you're still in trouble let us know :)

resize the HDR-Image to something like W 360 x H 180 px and blur it in order to get rid of blotches.
