How can you work with AGx and .exr files (exported from Blender with Agx color profile) from Blender in Gimp? Any solution for that? Also I can't open .exr filer in Olive. Not supported.
I am, yes. However, "reaching white" shouldn't be the goal in any scene, as that would meqn you're overexposing and losing information. If you absolutely need to do it, and understand the implications of it, you can add any of the adjustment layers after the convert colour space node. Good luck!
Unfortunately you need a special transform for this. Essentially you need a "None" or a "No operation" transform in your OCIO config. Which is a bit of work to do. You then need to use that transform in Blender Colour Management settings. In the Convert Colou Space node, you then select Linear BT.709 and the output as AgX.
Sure. You will need to copy the LUT folder into the Blender's Colour Management folder, and copy parts of the AgX configuration file. Or you could use a configuration that includes many different setups, like the one @GencoUney has shared. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RigdyzR_cf0.html
You can use it in the Fusion tab. Add an OCIO Colour Space node. However, you will need to do a lot of grading in Fusion, "before" the OCIO Colour Space transform (Before your Linear data is transformed to AgX). You can then add finishing touches in the Colour tab. Not ideal. We need to wait for the DCTL.
