Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

PhysX crash on play with World Composition


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: Test Project

  • 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!

Product Version: UE 4.15
