I couldn't find anyone else having this issue, but since I got the newest Substance Painter all materials that I've tested displays a vastly different color than previous Substance Painter versions. It appears to be the materials themselves doing this as a plain fill color shows correctly.
The main materials I've focused on testing is Resin Epoxy and Bull Leather medium grain. (but it appears it's most if not all materials). It displays best with the color #F8A73B, that previously showed up on these and other materials
close to the actual hex, but now turns from yellow to bright orange.
Thanks for any advice.
Example of same project and same color on old vs new substance.
