Hello,

We are creating obi rope procedurally, everything works fine. But after loading a new scene or reloading the existing scene, unity editor crashes with above log after creating a new ObiSolver with new blueprints.

We tried destroying obifixedupdate, solver, colliders before loading a new scene but the problem still exists.

We need your assistance.

Best regards.

Hi,

Which Obi and Unity versions are you using?

As a note, the stack trace reveals you're using the fallback backend (Oni) which is only used when you haven't installed the required packages. It has poorer platform support than Burst and it is also slower, for these reasons it's been deprecated and will be removed in the next major update. So make sure you've properly installed all required packages as per the manual:

http://obi.virtualmethodstudio.com/manua...kends.html

kind regards,

Thank you for your fast reply.

Problem solved after updating ObiRope to 6.5 and installing required packages for using Burst backend.

My Unity version is 2021.3.9f1
