Most definitely is a gamma problem, yes. This is not for game graphics, but for film.
I don't think it's the .exr, or redshift, but how Gaea ranges it. Does that make sense?
What it spits out looks washed out like renders before gamma correction can look.
Redshift handles Linear exr with no problem. Maybe I'll stick to 16bit tif from Gaea.
"In film production, we almost never use 8-bit textures for color/albedo, because of banding, etc. (JPEG is especially problematic since by spec, it's sRGB rather than linear values.) We either use 'half' (16 bit float) or 16-bit unsigned integer values for color/albedo textures." -Larry Gritz
8 bit texture are also linearized internally in the redshift
Maybe I'm missing a gamma setting in Gaea, after all, I'm new to this software.
Thanks
