Your bug report should include:
What happened: I don’t think this really counts as a bug, so much as a question about the difference between an Overlay and Scene View of a given texture. The example I have has a relatively light albedo, as shown in the Overlay View (see screenshot) but the color is darker and more saturated in the Scene View. I did not connect a shadow map, but I did use AO (which seemed to lighten things a bit more than it was without it).
Does it happen consistently, or randomly? I have not had a chance to create an alternate scene to test this out further. If it’s just a property of how materials are rendered in PBR mode, is it safe to assume the same asset would render as darkly in another application? I’ve run into trouble with producing accurate colors due to things like monitor settings, which can sometimes force me to correct for it sort of by eye using a reference color table or something like it on a screen that has bad color (usually because I can’t change the settings it’s using).
The steps to reproduce it. Include a screenshot or world file if possible:
