This asset defines data for shrapnel.

Format (Headers)[edit]

zShrapnelAsset[edit]

The asset data starts with a 0xC byte header:

Offset Type Variable Description
0x00 int fassetCount Amount of frag entries
0x04 AssetID sharpnelID This asset
0x08 int Unknown, always 0

After that, there's an array of shrapnel entries, as defined in the header. Each entry is of variable size:

  • Type 1 (Group)
  • Type 2 (Shrapnel)
  • Type 3 (Particle)
    • BFBB - 0x1D4
    • TSSM - 0x1F8
  • Type 4 (Projectile)
    • BFBB - 0x90
    • TSSM - 0x110
  • Type 5 (Lightning)
    • BFBB - 0x68
    • TSSM - 0x70
  • Type 6 (Sound)
    • BFBB - 0x4C
    • TSSM - 0x44
  • Type 7 (Shockwave)
    • TSSM - 0x54
  • Type 8 (Explosion)
    • TSSM - 0x48
  • Type 9 (Distortion)
    • TSSM - 0x5C
  • Type 10 (Fire)
    • TSSM - 0x5C

zFragAsset[edit]

The entries have the following structure:

Offset Type Variable Description
0x00 int type
  • 0 = eFragInactive
  • 1 = eFragGroup
  • 2 = eFragShrapnel
  • 3 = eFragParticle
  • 4 = eFragProjectile
  • 5 = eFragLightning
  • 6 = eFragSound
  • 7 = eFragShockwave
  • 8 = eFragExplosion
  • 9 = eFragDistortion
  • 10 = eFragFire
0x04 AssetID id
0x08 AssetID parentID
0x0C AssetID parentID2
0x10 float lifetime
0x14 float delay

zFragLocation[edit]

Every entry/frag (except shockwave) has this header at a different position.
Sometimes it only has 0xCD padding bytes.

Offset Type Variable Description
0x00 uint type
  • 0 = eFragLocBone
  • 1 = eFragLocBoneUpdated
  • 2 = eFragLocBoneLocal
  • 3 = eFragLocBoneLocalUpdated
  • 4 = eFragLocTag
  • 5 = eFragLocTagUpdated
[Frag] Bone only
0x04 int index
0x08 Vector3 offset
0x0C uint[4] Padding - 0xCD bytes, 4-byte alignment
[Model] Tag only
0x04 Vector3 v
0x10 uint matidx
0x14 float[4] wt Always 0xCD padding bytes?
0x24 float rand_radius Not present in BFBB
