Really? I thought Linear Dodge was an add operation. Have you tried Fusion, if so what's your opinion?

you are quite right Linear Dodge is a simple l1 + l2 operation so plus, can't believe that slipped my mind i'm getting old DO'H, and there are of course ways to unpremult an alpha in PS as well it's just a PITA I'm not trying to put anyone of PS ;)

I've no real experience with fusion, but i hear good things so...

Thanks for the info.
Definitely going to try Nuke. After I learned the Mila material and how to use passes.

hi everyone! i have a problem with color management in maya 2016. My render is too light.

I'm following the gnomon tutorial and set up a material, in the lesson fresnel is off, but i decided turn it on, and got this

but is still too light, so i decided turn color management off and i got better result, but i realize that it's incorrect.

any advises.
p/s sorry for my english:beer:

It looks like you have physical sun and sky for this, which may add an additional gamma correction of 2.2 for your camera via an mia_exposure_simple node, I think. Checking in Maya 2016.5, it doesn't appear to do that anymore, but that could be my setup. So I believe with color management on, you would get double the correction, which you don't want. Either disconnect the exposure node from your camera, or turn the gamma correction to 1. I hope that's the solution.

thank you very much!
