Description

The LOD switching when the simulation is paused could still be causing problems when the simulation is paused while the LOD indexes are going up because there is no LOD Bias mappings by default.

See:

Previous fix CL#45595781 only works when the LOD index is going down.

Steps to Reproduce
  • Find a SKM that has different cloth meshes for different LOD levels
  • Add an actor with a SkeletalMeshComponent to a map and assign the SKM. Make sure the physics work in PIE mode.
  • Start PIE mode
  • Start recording in the rewind debugger
  • Move the camera back and forth to enforce LOD changes
  • Pause the game (not sure if it matters, but do not stop PIE mode, just pause it)
  • Scrub in the rewind debugger by dragging the timestamp marker left and right (vertical line)
