Bug / Crash Obi rupe irradic on start (Unity)

[frg_kova]

Hey guys. I have a big problem, all the ropes are wild when you hit play. They seem to come from world origin (0,0,0) and snap into place, but that pulls/applies force to rigidbodies ends are pinned to.
Any ideas? There's no scripts or physics affecting it, it's only rope in this scene, screenshot for the first frame. Thanks for your help!

Hi,

Can you describe your object hierarchy in detail? Where are the rigid bodies in relation to the colliders and the rope?

Hey, yeah, they are all siblings parented under one game object.

Parent prefab
  Hook1 - rigidbody, box collider, obi coll. etc
  Hook2 - rigidbody, box collider, obi coll. etc
  ObiRope - rope, pin constraints for endpoints to Hooks

Can't reproduce anything similar here, using an identical hierarchy. However we did fix a couple pin constraint related issues in 4.0.2, try updating and see if the issue persists.

It's fixed in 4.0.2

from changelist it's apperent one or both of these fixed it
- Issue with pin constraints overshooting when solver set to world space mode.
- Issue that prevented pin constraints being torn.
