Hey
I've noticed a massive difference in render time between when I start the render with Colormapping_Gamma on 2.2 or on 1.
I'm not using Corona's own colormapping as I'm using Maya_2015 new color management system and I'm using a Custom LUT, but when I put the Colormapping_Gamma at 1, it is much much longer than when it is on 2.2, and I can see that it's sending a LOT more samples when it's on 2.2
Any reason for this? I've read somewhere that brighter images were longer to render, so I was wondering why it was the opposite here.
Here's a couple of images
You can see as well that if I put the gamma back to 1 AFTER the render is complete, the image is identical.
Render started with Gamma at 1 (ColorManagement ON)
Render started with Gamma at 2.2 then reverted to 1 after the render completed (ColorManagement ON)
Gamma at 2.2 with ColorManagement ON
Gamma at 2.2 with ColorManagement OFF
I find it a bit obscure, so I thought there might be an issue somewhere. I don't mind using Corona's Colormapping but I'd much rather using my custom LUT.
If anyone knows why this is happening, as it's a really stranger behaviour to me.
