HELP, i was importing c4d files using datasmith and cannot simulate physics. If i do import fbx it can simulate physics, i wondering what is the diffrent, i found the object from DATASMITH are have 0colission prime. How to enable the datasmith import object to be enable in physic? thank you!

Guessing you figured it out by now, but for anyone else: the imported meshes need collision objects, as collision is not automatically generated when importing.
