Solver is too performance heavy

[chenji]

Hello, I have received fixed project. I’ve tested it, but it doesn’t seem to work properly under high forces, even without torque. Could you share a quick summary of what you did to fix the gap issue? It’s possible I missed something during implementation or the setup didn’t install correctly.

Best regards

If it does not work only under large force, it usually means the solver (Obi's and/or Unity's) cannot handle large acceleration properly. The solution is:

1. Increase Obi solver's substep and/or decrease Unity's fixed timestep
2. Instead of do #1, probably a much easier solution, increase your object's mass where the force applies on. Or manually clamp the velocity to a low value.
3. If there is still a visual gap, you can do what I mentioned in my previous posts, hook an event handler of Obi Solver and manually align the position as a last resort. If you're using attachment, in 7.1 you can use projection=true to let Obi do this automatically.
