Changing scale of static mesh causes break

Development Asset Creation

  1. Create an actor blueprint
  2. Add a sphere or cube mesh as a component in the actor.
  3. Change the scale of the static mesh component from [1.0,1.0,1.0] to [0.1,0.1,0.1]
  4. The very first time you change the scale from 1.0 to 0.1, the engine will break on “NavigationSystem.cpp” at line 2493 because “OwnerActor” is null, though “comp” is a valid value with "Comp = (Name=0x0000000146adbd00 “Cube_GEN_VARIABLE”)
  5. If you continue debugging, you can change the rest of the scale values without hitting any break points. Once you have done this once, you have to restart the engine to reproduce the problem (I think this has something to do with cache).
