Vectorworks to TwinMotion Workflow problem

Hello there,
I just started using TwinMotion as a rendering programm, coming from Lumion 10 i never really had problems importing my CAD projects into Lumion via Collada. But now in TwinMotion i don’t really get good import results, i tried c4d, fbx, obj, but none of them really work good. The big problem is, that most floor textures won’t apply correctly.

As you can see only the Wall has the Texture applied correctly and the floor doesn’t.

Thx for your help,
