(Required Blender 3.3-3.6 and CM3D2 Converter) Install: Overwrite anm_export.py in cm3d2 converter folder

All Frame "Export All Frames" checkbox ON

• Use for maximum compatibility
• File size: Full size (no optimization) or use bone filter (maybe reduce 30-50%)

Optimized Export (Recommended)

• "Export All Frames" checkbox OFF
• Reveals Keyframe Optimization options
• Use for file size reduction

#Optimization Methods#

SIMPLE

How it works: Keep every Nth frame uniformly Frame Step = 2: Keep frames 0, 2, 4, 6, 8... Frame Step = 3: Keep frames 0, 3, 6, 9, 12...

DENSITY

Settings:

• Dense Bone Threshold (0.1-1.0): When to consider bone "dense"
  • 0.8 = bone with >80% keyframes is "dense"
• Dense Bone Sampling (2-5): Reduction factor for dense bones
  • 2 = keep every 2nd keyframe from dense bones

MOTION

Settings:

• Motion Threshold (0.001-0.1): Minimum change to keep keyframe
  • Lower = more sensitive, larger files
• Time Gap Limit (5-30): Max frames between keyframes

---

RDP - Curve

How it works: Ramer-Douglas-Peucker curve simplification Settings:

• RDP Tolerance (0.001-0.1): Curve simplification tolerance
• Lower = more accurate, larger files
• Min Frame Distance (1-10): Minimum frames between keyframes
• Higher = fewer keyframes, smaller files

Recommend setting

-SIMPLE: Frame Step = 2 -DENSITY: Threshold = 0.6, Sampling = 2
-MOTION: Threshold = 0.005, Gap = 5 -RDP: Tolerance = 0.005, Distance = 1
