Hi iremuyg !
Glad you like the plugin 
Have you checked that the geometry’s mobility of the objects you want to use physics on is set to “movable” and not “static” ?
By default the plugin will import geometry with the mobility on “static”, and physics will not work on the objects.
If you need to toggle it on your entire assembly, you can use Visual Dataprep and the “Set Mobility” operation.
Cheers !
Antoine
