PhysX crash on play with World Composition

Development World Creation

Hello,

We recently tried upgrading from 4.13.1 to 4.15.1, and we use World Composition with a very large map.

After upgrading, when opening the persistent level we started getting a very consistent PhysX crash on play. After some investigating it seems to be related to World Origin Rebasing.

Here’s the repro steps we have:

  • Enable World Composition
  • Enable World Origin Rebasing
  • Add a sub-level and move it far from the origin in World Composition (far enough to force rebasing to happen)
  • Add a skeletal mesh with collision enabled to the sub-level.
  • Add a PlayerStart at the location of the sub-level.
  • Play

I’ve also attached a project here with a repro case:

  • Open the Master_2017 level.
  • Press Play: There should be no crash.
  • Enable World Origin Rebasing
  • Press Play: Crash

At the moment without a fix for this we’re unfortunately having to revert back to 4.13.

Thanks for any help!
