Thank you both.

Hello!

I create 3d maps using SketchUp and then I import them to Unity.

I import different layers to sketchup that contain only one type of data i.e. one layer for walls, one layer for rooms. I need every room in the rooms' layer to be separate object (mesh) but in the same group when i import it to Unity. Is there a (quick) way to do this?

I thought of making separate layer for every room and then group them in one group in Unity but it's a lot of manual work.

Any help will be appreciated.
