SketchUp Crash When I import a Second VRScene

Hi,

I have a problem when i import a second VRScene.
I have the same model in 3DS, i export into VRScene with blue material, and a second type with an orange material.
If i want to import the blue AND the orange, SketchUp just crash immediately.

I make a mistake somewhere? Do you have an idea?

Thx

EDIT:
If i copy/past from an other sketchup, it’s OK.
Maybe it’s just a bug from VRScene Importer
