Expanding on the very limited default Autodesk offer. Based on Maya config with some functionalities from the one from Max so everyone should be fine (although I removed some not-so-common hdr displays from the config).
feedback is welcome. for example would and option to create your own view transform (the easy way: grade for example in Affinity, save as a lut, put it into the config folder - done) be interesting?
Hah! Same…I just play with things until I find a recipe that doesnt crush my brights too much, doesnt shit on my midtones, and has nice falloffs and colour / light bounces…Im not sure I’ll ever grasp the inner workings of it, especially now that I work from home, solo on just about every project.
Okay, so maybe I’m a bit confused or maybe I guessed correctly, so I will say what I did and somebody can say if it is wrong or otherwise.
In Max’s colour management I switched to Unmanaged.
I load the OCIO above into the vfb, setting the input space and display to sRGB, then choose one of the transforms.
Hopefully I got it right and will have learned something today
no need to get to deep into the math.
it all boils down to converting data (colour data from a render engine or camera) into nice images on screens. I think for some reason part of cgi industry not close to cinema was a bit behind in that matter. instead of copying what camera manufacturers already figured out (transition from film to digital and keeping the “look” intact as much as possible) we were using just simple S-curve based tonemapping methods.
calling them filmic was not enough to get us the visual quality we were used to for over one hounded years of cinema and even more of photography.
ocio is just convenient delivery system for all the math involved in putting data on a display. every camera is accompanied by a slew of luts that do this work and now we have streamlined access to all that and more.
big misconception about aces system is that we need it to get nice film-like contrast and pleasant highlight roll-off. but you can do that with a simple lut. there is probably more than 10 more established and loved “colour recipes”. aces being a standard is quite an overstatement. its as standard as DWG colour space in Resolve, very similar concept just more opened.
regarding your recipe: do you think you could get a better looking image with AgX display transform and some curves adjustment below (so adjusting linear colour, not intuitive but you can get used to it) or aces is close enough to what you are after?
I did noticed that while agx looked good, it did lack contrast, so I switched to aces as a preference or agx with further curves or whatever. It’d definitely be interesting to see what an adjusted agx would give.

Hence my wish for a kind of “camera calibration” curve that mimics the look of different camera models.
I know there are ways to do this, but never got the time to evaluate this fully.
it would be more complicated than a curve or even three - more like a 3D lut. you can hop on Sony website, get the luts and done - you have something like a “default” Sony look.
