View Full Version : Physical sky with frame buffers gamma problem

Hi,
I posted this in another thread but think it was a bit off topic and warranted its own thread.

I'm finding that when using physical sun and sky, the gamma of the beauty render without using frame buffers is very different to when they are used. I've no idea what's causing it, but it's basically resulting in everything being blown out.

The only shaders being used are mia_material and fast_skin_sss (which are both affected).

Would really appreciate it if anyone knows why this is happening, and if there's a decent fix

EDIT - Might be worth mentioning that playing with the gamma in mia_exposure_simple node has no effect on the rendered framebuffers

I got the same problem here in Maya 2009. Seem the mia_exposure_simple has no effects on the passes only to the final image. Anyone knows how to get it work on the passes?
Thanks

The production shader "mip_gamma_gain" should help.
