Hey matthewsmall,you need to tell Unreal how to interpret the maps correctly.Substance exports he maps correctly in linear and srgb colour space, but Unreal interprets the linear maps wrong by default. I don't know why, to be honest.You can double-click the imported texture and uncheck the 'sRGB Colour' checkbox. You need to do this with the height, roughness and metallic.If you already set up a material you need to reimport the textures there or change the interpretation there as well, but reimporting the textures into the material is easier Best regards
I am actually having the same issue. I've got a completely procedural substance that I have made. Looks great in Substance but in UE4... like... ehhhh....I read the suggestion on disabling the sRGB but that did not seem to do anything for me and the appearance in-level did not change at all.Am working with imported substance with instances as created by the plugin upon import.
