Source code	zShrapnel.h

This asset defines data for shrapnel.

Format (Headers)

zShrapnelAsset

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

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

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
