Hi to the team!
I have to report an issue regarding textures: usually, the "additional" maps (bump and roughness) should take the same UVs as in the diffuse slot used in sketchup. At the moment, instead, the additional textures are applied a default mapping, so they result disaligned with the diffuse texture. You can correct the alignment by enabling the explicit map transformation and manually input the dimensions of the diffuse texture used in SketchUp but that's clearly a bug that needs to be fixed.
At your disposal for further information, if needed.
