UAnimInstance::RecordMachineWeight
#include "Animation/AnimInstance.h"
Access: public
Description
Records the overall blend weight of a state machine for the current animation update, used by debugging tools such as the animation Blueprint editor's state machine weight display.
Caveats & Gotchas
- • Purely bookkeeping for debug/inspection purposes; it does not affect evaluation or blending, so calling it with an incorrect weight only misleads the debugger, not the actual pose.
- • Called automatically by generated state machine node code — hand-authored calls are only useful when hooking custom state machine logic into the existing debug display.
