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?
