Help Scripting rod forces

[josemendez]

Well it comes from the script, but I don't know how to move/rotate rod to avoid various negative effects, like this one.
Rod is not straight, but I tested just in case with straight one and it does not matter, but except that yes, I added only angularVelocity.
I am going to send you example scene.

Hi!

Just answered your email, the problem is simply that your angular damping is way too high and this jeopardizes stability. The only two possible solutions are to reduce damping or reduce the global timestep (Project settings->Time->fixed timestep)

Keep in mind that velocity-based approaches in physics are not unconditionally stable, so extreme values *will* cause things to jitter and eventually explode. This is just a basic consequence of how numerical integration works.

kind regards
