Hi @BigRoy,
For the alembic camera, you can use c4d.MSG_GETREALCAMERADATA, for example:
def main(): data = dict() op.Message(c4d.MSG_GETREALCAMERADATA, data) print(data['res'])Another option (which would work for other object types as well) would be to check type of the object's cache using GetCache().
Cheers,
Ilia
