Blend Per Bone

Animation Blend Per Bone Implementation

• Split Animation Layering Setup

• Issue: Full animation plays during movement (gliding effect)
• Solution: Split animations between body parts
  • Top: plays attack animation
  • Bottom: plays locomotion

• Animation Blueprint Configuration

• Create cache for locomotion state

  • Drag locomotion pin → search “cache”
  • Name: cache_locomotion
  • Rearrange default slot before dodge
    • “Ensures montages don’t play during dodge roll”

• Layer Blend Per Bone Setup

  • Search/add “layer blend per bone”
  • Connect to dodge roll’s false pose
  • Configure bone settings:
    • Add branch filter
    • Copy spine bone name from Skeleton tab
    • Paste name in options
  • Connections:
    • Default slot → blend pose zero pin
    • cache_locomotion → bass pose

• Standing Animation Enhancement

• Use ismoving variable with blend by bool
  • Place before dodge roll
  • Save default slot to cache_defaultslot
  • Connections:
    • Layer bone node → true path
    • cache_defaultslot → false path
    • “Full animation plays when standing”
    • “Split animation plays when moving”

This system creates a more polished animation by splitting body movements between top and bottom, while maintaining full animations during stationary attacks. Small adjustments significantly improve overall animation fluidity.
