I think i figured it out while i was collecting more info (as usual )
The scene structure in short:
- The robot is made of ArticulationBodies (~100 mass)
- A simple RigidBody box is attached to the robot with a FixedJoint (1 mass)
- The Obi Rope particle is attached to the RigidBody
I guess what's happening is (please correct me if i'm wrong) that in each update, first the rope pulls the RigidBody in place, and then because the robot is much heavier than the RigidBody, the FixedJoint pulls back the RigidBody to the robot and only applies minimal force on the robot. Changing the MassScale/ConnectedMassScale settings of the FixedJoint seems to solve the issue.
Hi!
Yes, your findings make sense. If the rope is acting on a rigidbody and the rigidbody is much lighter than the robot, the fixed joint will pull the rigidbody towards the robot (instead of both towards each other or the robot towards the rigidbody, which woild be the outcome for equal mass and heavier rigidbody respectively) so very little of the force applied by the rope on the rigidbody will affect the robot.
