Havok Aware Bullet Counted Reload (HaBCR)

Description

A modern bullet counted reload system that directly controls Havok Animation.

HaBCR reads custom annotations (HaBCR_LoopStart, HaBCR_LoopEnd) from your animation files and handles reload looping automatically at the engine level. Animators only need to mark where the loop begins and ends — HaBCR takes care of the rest.

Also compatible with existing BCR-style weapons through fallback support.

Main features

Annotation-Based Loop Control

- Uses HaBCR_LoopStart and HaBCR_LoopEnd annotations

- Animators mark loop boundaries; HaBCR handles the looping

- No need to animate full magazine capacity — one shell insertion animation is enough

Direct Havok Integration

- Accesses hkbClipGenerator directly

- Uses setLocalTime() for precise animation rewinding

- Frame-accurate loop timing

Universal Compatibility

- Works in 1st person, 3rd person, and Power Armor

- Supports tactical reload framework

- Clean reload interruption via R key

BCR Fallback Support

- Weapons with HaBCR annotations → Annotation mode

- Weapons without annotations → CullBone/UnCullBone fallback (BCR mode)

- Most existing BCR weapons work without modification

Lightweight

- No ESP/ESM

- No Form ID dependencies

- Configurable via INI (Data/F4SE/Plugins/HaBCR.ini)

This mod is not a BCR bug fix mod. It cannot completely resolve bugs that occurred when using BCR.
