Metal roughness settings

Hi all first post here :).
I m having an issue with my roughness metalness and occlussion maps I try to export from substance painter(simple steel material) but i cant find the correct settings and rough/metalness shows black.
I unchecked the srgb and switches sampler type to linear color but still black. I also placed a reflection sphere that doesn fix it.
Anyone can help ?

Thanks in advance and cheers all.

hi.i’m a beginner too.and welcome.
i think you should put an spherical reflection capture in the scene.
have fun here…

I said i did its not the reflection probe…

Hi, I would try building the lighting. Sometimes that fixes it. If not, try disconnecting the metallic value. Sometimes that can be finicky.
