Meshes disappearing when running outside PIE

Initial observation of problem in packaged game.

  • Mesh of force-field actor and top of lift actor dissapear
  • Also force-field behavior stops (triggered by an unoverlap when meshes dissapeared?)
  • At this time the force-field was welded to the top of the lift mesh.

The project contains some c++, but not much.

My game had been working fine until I packaged. Then I had some meshes and actors disappearing.
I’m able to print debug their transform location, so they haven’t been killed, but their meshes don’t render.
Sometimes my Player’s mesh will also disappear, and I lose the ability to crouch.
These problems are not predictable.

I created a map to try and identify the differences.

PIE - works perfectly

Standalone launch - has these missing meshes every time

Launch/Packaged Game - has occasional problems with missing meshes. In this case, it is correct.

I don’t know how to test these errors, as they never happen in PIE.
