What versions of MtoA? And you should check the Arnold log from both renders. And Maya 2107 has a lot of changes for color management.
The difference is I get a much darker image in 2015 than in 2017. And it's not a straight gamma correction issue. I played around with the scene scale and got close but not the same. But the issue is I shouldn't have to change anything.
What versions of MtoA? same or different?
Hi Manny, could you post some images so that we know what kind of differences you're talking about ?
There have been major changes in MtoA for Maya 2017, regarding color management.
You'll find more details in the documentation
Hi Sebastian, I can't post an image. In crazy delivery mode. But I surmised that it was a color management issue. I was hoping it was a straight gamma correct in the comp. But it wasn't. So we wasted a lot of render time tracking this down.
