Problem With CMasking_MaskRGB Dark pixels On edge

[pixiesrip]

Hi! I have dark pixel probably coming from the AA when i'm trying to render object Gbuffer and Materiel Gbuffer in RGB mode.
Perhaps you have an idea to solve the problem. I have tried the wirecolor masking but same problem with an RGB wire.
Attached the same element render in Vray with Multimatte RGB object

Please, Someone?

Hi, sorry but I do not fully understand the problem. Can you tell us more precisely what is the expected result and what goes wrong? What are you trying to achieve / what is the goal?

"I have dark pixel probably coming from the AA" - I do not understand this.

Maybe he means that when he colour corrects in compositing using the element as a mask, he is getting a dark edge?

I can confirm this problem exists. It is caused by the image being saved with incorrect gamma - after applying gamma 1/2.2, everything looks correct. There are other bug reports on this topic, so I will close down this one as duplicate - see https://forum.corona-renderer.com/index.php/topic,8747.0.html. We will try to find solution soon
