I attached the hip file.

I did a test and accidentally found this weird result using geo VOP inside the dopnet.
I create a box and split it into 2 pieces then send them to dopnet. Inside the dopnet I add rigidbody and a geometry VOP. Inside the geo VOP , I simply add 'import point attribute' node to fetch the "P" from itself then wiring the output to the output.

This suppose to be the same like using bind to fetch P, or by wiring from geo global var P directly to output P.

When I play the sim, it got some angular velocity from nowhere. I should stay still.

When calculating center of mass, the pivot point is changed.
So, the pivot of incoming object and that of dop object differ, causing problems in setting P.
