Fix: Unreal Physics Asset Recreates on Every BP Compile

Each BP compile takes 30s; profile shows physics asset rebuild.

Decouple from BP

Reference via default SkeletalMeshComponent; not class-level. Recompile doesn't ripple.

Or split asset

Physics asset and BP in separate compile units. Decoupled rebuilds.

Audit compile graph

Each BP's dependency. Physics asset dependence is usually unintentional.

“BP compile dependencies cascade. Decoupling saves time.”

If your compile times are long, the dependency graph is the bottleneck. Audit; restructure.
