I'm having a problem with affinity photo not transferring exr files rendered in blender with the color transform chosen inside blender. I remember this having worked in the past, so I don't know wether I accidentally changed anything.
I rendered an image in blender with a filmic color transform and saved it as a 32 bit exr. Here is what it looks like in blender with the color management settings.
And here is what it looks like upon opening the file in affinity photo. (Side-by-side closeup). The highlights are over-exposed and it looks like the srgb color transform in blender.
So I tried using an opencolorio transform in affinity photo, however I am unable to select any color profiles and the transform option in the 32 bit preview window in greyed out, despite having selected a opencolorio configuration file in the settings.
