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!
