That’s a pretty deep rabbit hole. If this really is a necessary shenanigan for such a thing to work, it’s the first I’ve heard of it, but perhaps that’s just because I was using textures that were already using the appropriate color space.
Was it just a texture you had imported via Unity? Or was it the result of some graphical calculation? Because there is that sRGB setting you can fiddle with on import, but I have far from a complete mental picture of all the parts it might change.
This doesn’t look like gamma/linear issue. It looks like the brown/sand colors are rendered as white in the PNG: gamma/linear conversion would just impact their brightness, it wouldn’t turn something white if it’s not.
I wonder if Unity saves it in a slightly different PNG format that windows explorer doesn’t understand. Does any other image viewer agree with Unity’s interpretation of those colors? It could also be a bug in the Unity PNG encoder…
Good point… OP… what happens if you test-save as JPG?
