Long standing “issue” I’ve always dealt with but thought I’d ask in case anyone has had a similar experience.
When using fairly default settings in Maya Vray for rendering, there’s always a pretty noticeable discrepancy between what’s shown in Maya vs. how the rendered EXRs look when brought into Flame. Back in the day I used Scene Linear Rec 709 to tag the files, recently I’ve tried ACEScg, doesn’t seem to be any difference on how they’re displayed in Fame. Renders appear to be flatter, have less contrast, saturation and tend to lean more green when viewed in Flame than they do in Maya.
I’ve gotten used to coloring them back to what they “should” be, but I just wonder if I’m doing something “wrong” along the way to cause the discrepancy. Realize there could be many different variables effecting this scenario, but does anyone have the secret sauce to get Maya/Vray for Maya and Flame more alligned?
Yup, it’s not ideal, but in my world, I’m doing the renders and the comps, so it’s ok if it’s not “perfect.” That being said, I still don’t know why I have this discrepancy.
As requested, here’s a side by side. As you can see, Maya is set to OCIO correction, ACEScg. Flame is set to the default View Transform for ACEScg. Not sure what else I could be doing wrong.
But like I said, this has been like this for me for over a decade. Back before modern color mgmt. Scene Linear displayed as Rec709 in Maya has always looked different than Scene Linear displayed as Rec709 in Flame. I don’t know or care which is right, just would love for them to match.
Maybe someone with Maya can help out with these settings. What’s visible in the screen is the input color space and the viewing transform. It doesn’t show what may be happening during the render.
I think I may have found the issue in Vray… setting it to display OCIO results in the screenshot above. Changing it to gamma 2.2 results in more of a match to Flame’s view transform for Aces to Rec709.
Is there a transform in Flame that would match the OCIO result in VRay?
ugh, color science… I was doing a simple View Transform on the clip using the “default” rules in Flame. Perhaps given the fact that I haven’t actually assigned color management to my project, I had just assumed it would know what to do with ACEScg. Clearly that assumption was wrong. If I change my View Transform from “From Rules” to “ACES 1.1 SDR-video” I get a result much more in line with the OCIO transform in Maya.
So I guess I’ll just make sure I’m using those rules from now on.
Thanks for helping me talk it though and sorry for the noise. Sometimes I expect these things to just work “Automagically” and I don’t think that’s always the case. Or I am incorrectly setting up Flame to work its magic the way it wants to.
