With regard to the color space talk, I happened to have closely investigated what H20 is doing just yesterday. The issue I was running into is that Karma’s output respects the Input File Rules set up in the OCIO editor (Edit > OCIO Settings…). So even if your working space is set to ACEScg, the rendered image will still be linear rec.709 unless you take some step to prevent it.
\n– You can put the string “ACEScg” in the render’s filename, and Karma will obey the file rule. – You can change the file rule for *.exr to ACEScg. If you’re already pre-processing your inputs, this is what you should do. This is the “correct” ACES workflow. – You can set the Output Colorspace parameter for each AOV that should be ACEScg. – Or you can use the OCIO filter in the render settings to apply a post conversion. I recommend against that one, though, as I do not believe the conversion is lossless, and it risks a double conversion.
\nThe SDR 1.0 Video view transform from ACES 1.3 ought to be sufficiently visually similar to Output – Display – sRGB from ACES 1.2, but I haven’t verified that yet. The Un-tone-mapped view should be the same as Input – Texture – sRGB.
\nThe ACES 1.2 config can be found here: github.com\/colour-science\/OpenColorIO-Configs\/tree\/master\/aces_1.2<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
