Substance material not rendering right on multi-element meshes.

Hello. I am pretty new to unreal, have used 3Ds max in the past.
Here’s my problem:
1.I Import a substance material into Unreal.
2.I import an armchair into Unreal.
3. I drop the armchair (total 4 elements)from content browser into the scene.
4. I apply the substance material , different materials to different elements(fabric)(the one that previews correctly as a sphere in the content browser.) To the armchair.
5. I put in reflection capture.
6. I put in skylight.
7. I build the scene.
8. I press play, but the materials just show as basic colours, no roughness , no specular, no normals.

I looked up everywhere and could not troubleshoot the issue. I read that there might be an issue with sRGB or the texture coordinate index , but no one really explains WHAT the issue is and how to resolve this.
I am sorry if I am sparse on information, please ask what you have to and I will explain more. I have the substance plugin up and running, the materials show up nicely on the floor, cubes,etc, but not on imported multi element meshes.
Any help appreciated!
Thanks!
