Material gloss

So i have been trying to import a selection of textures however they where too glossy compared to substance.
I know how to plug everything in. I’m familiar with checking srgb and making it linear colour, however certain textures when imported begin having srgb already unchecked and are locked that way- when those very select ones are changed form normal to linear colour the error it gives cant be fixed. Because of this issue I cannot fix the glossiness.

any response would be very appreciated :slight_smile:
