Blueprints In-depth - Part 2
summary
Blueprint compile time scales with node count and references, and casting causes chain recompiles that can freeze the Editor; an extreme test goes from 52 seconds to 1.3 seconds when logic moves into Functions. Blueprints historically hit a 64 kilobyte limit (compile failure if exceeded). Practical fixes: prefer Functions, use Interfaces and tags instead of heavy casts, bridge with tiny C++ accessor Functions and Events, guard with IsValid, and mark intentionally disconnected nodes as Disconnected On Purpose to avoid confusion. Other tips: Show 3D Widgets, use String Tables, Maps and Sets for content.
