Change the substance of only one object
Hello,
I just started with dimension 3.4.5
I'm trying to import an 3D Object in Dimension.

The object is well opened in Dimension.
But When i'm trying to change only the material for only one sphere, it changes the material for all object.
I'm trying to dissociate, ungroup, ... the objects, but it's the same.
It's like if all the sphere are the same.

Could you help me ?
I'm trying to do something like that.

Thanks.
Cyril
