LogLinker: Warning: Unable to load PhysicsSerializer message with 4.22

I updated my project to 4.22 and now I’m seeing this message:

LogLinker: Warning: Unable to load PhysicsSerializer with outer HierarchicalInstancedStaticMeshComponent /Game/HVAC/Blueprints/BP_RectDuct.BP_RectDuct_C:Segments_GEN_VARIABLE because its class does not exist

The blueprint in question creates a daisy chain of instanced static meshes along a vector defined by two end points. The mobility is set to stationary. They appear in the game level, but it seems the collision is now missing. How to fix this?

I’m running into the same issue…ever find a fix? :slight_smile:

Same issue, interested in solutions…

It’s been a while, but I believe my fix was resaving:

  • Base blueprint class in question
  • Any child blueprint classes deriving from the base
  • Any instances place in the a level

Try renaming BP_RectDuct
