Breaking Down Complex Blueprints

1. Identify Natural Boundaries

   • Logical functional groups
   • Independent operations
   • Reusable sequences
   • Data processing stages

2. Refactoring Strategies

   • Collapse distinctive functionality into dedicated functions where possible
   • Collapse repetitive execution flow patterns into macros
   • Collapse other functionality into a composite (collapsed) graph that may not work in a function or macro (eg. delays, custom events, etc.)

Translation Approaches

1. Incremental Translation

   • Translate core functionality first
   • Add supporting systems gradually
   • Test each component individually
   • Integrate pieces systematically

2. Partial Translation

   • Identify performance-critical paths
   • Translate compute-heavy sections
   • Keep simple logic in Blueprints
   • Balance maintenance needs

Note

Not everything needs to be in C++. It's likely fine to keep other less intensive systems in Blueprints if they don't benefit from translation. Unreal Insights is your friend!
