Investigation summary: - Tested velocity-based animation triggering: graph variable writes, animation events, character controller velocity manipulation, and Move() API calls - All approaches failed: animations do not play on SetPosition-backed proxy actors - Root cause: Fallout 4's animation system requires active AIProcess-driven locomotion packages, which are incompatible with networked puppet actors - Fallout 4's animation system fundamentally ties animation evaluation to the character controller's actual velocity AND active AI-driven locomotion state - PlaceAtMe proxies updated via SetPosition cannot provide either requirement Proxy actors currently work correctly for: - Smooth position synchronization - Heading/rotation updates - Jump animations (via Z-position) - Network sync and lifecycle What remains impossible without deep engine access: - Walk/run/sneak animation playback - Animation graph variable manipulation affecting behavior - Character controller velocity synthesis for puppets Recommendation: Accept this architectural limitation and provide alternative visual feedback (particles, glows, state indicators) instead of animations. Files changed: - plugin/src/F4TProxyActorController.cpp: Reverted to SetPosition-only approach - docs/dev-log.md: Added comprehensive investigation summary and conclusions Co-authored-by: Cursor <cursoragent@cursor.com>
