Step 8: Blueprints (blueprints)

Replaces deprecated Blueprint calls and compiles every Blueprint. It runs last, after all other steps have changed assets, so its compile result is the final state of the project.

Done automatically​

  • Deprecated function calls with a direct replacement are replaced, keeping every link.
  • Every Blueprint in the project is compiled.

Reported for you​

  • Compile errors, with fix text. For known errors UEAPM adds a precise fix from its compile hints.
  • Deprecated calls without an automatic replacement.
  • Node classes removed in UE5 (for example Matinee controller nodes).
  • Blueprints whose parent class was removed (for example editor tutorials).

Rule tables​

bp_nodes.json: 141 deprecated or renamed functions (14 replaced automatically, 34 already handled by the engine's own redirects on load, the rest reported), 4 removed node classes, removed parent classes and compile hints.
