Strange metall-roughness map

Development Asset Creation

Hi guys. There is an issue i’m trying to solve. I exported textures from Substance Painter 2.0.3 (UE4 Packed preset) and here is what i’ve got:

What the hack is that with metal-rough texture? It’s color looks strange to me. It should be grayscale, right?? :confused:

And - if that so, what i have done wrong?

Problem solved. Problem was in UE4 Packed preset. Standard one works pretty well. And of course un-ticking “sRGB” in the roughness and metalness map texture properties
