Hi, I'm using Cd point attribute to color packed intances with copy to point. My problem is Black gets a slight colored tint from hdr(I think) when using rgb4k_map.ppm in a texture_instance_color node(Color space is set to non-color data.
If colorspace is set to sRGB(texture_instance_color). Black is correct but other colors are incorrect(too dark).
2 examples. A uses vertex Cd, B uses point Cd(and copy to point packed instance), both Cd have 0,0,0 value. B render gets a slight purple tint.
Used contrast filter in affinty to make AB comparison more visible.
