Hey Mauro, that is very much possible as I've done it with vRay and Cycles passes. Every combination is different for each render engine though, so there would need to be separate videos (or at least separate sections) for each engine. I'll put it on the list!

Hi James, that's great. I have been working with V-Ray for the past 10 years at work (before that I was using RenderMan, Mental Ray and Arnold). Generally speaking, the main basic passes can be comped in the same exact way, though I appreciate that some of the most particular ones, like the crypromatte, normal and velocity vectors can come out quite differently depending on the engine. I guess something with the industry standards (V-Ray is definitely one of them), and just the basic passes will do as a nice starter. Thank you very much for getting back to me, and for considering putting together such tutorials. Very much appreciated! 🙂

Perfect! And please add some ACEScg, including 32 and 16-bit workflows. And how to best deal with specialty AOVs such as shadow- and cryptomattes in Affinity. I would give up Photoshop in a second if I could get comfortable with Affinity Photo for my render post-processing. Thanks!

Yes and yes-but the upcoming update will bring support for OCIO v2 (currently Photo only works with v1 configurations). Multichannel EXR files are brought in as multi-layered documents and you can composite everything in linear space. You can also open EXR files from Blender and then use my macros to apply both Filmic and AgX transforms non-destructively, no OCIO configuration required.

Please add cryptomatte support
