Model Info - .minfo¶

.minfo is the main file for any model. It describes how many lods a model has, the materials to use, how to read the .mmesh file buffer & more.

This file is a FlatBuffer file.

Field Name	Type	Description
magic	uint	Should be `20230729`, explicitly checked. Might correspond to a date, 2023/07/09.
lods	StreamLOD[]	Parameters for each lod. Each index corresponds to a `data/model_streaming/lod{number}` entry.
ShadowLODInfos	StreamLOD[]	Parameters for each shadow lod. Each index corresponds to a `data/model_streaming/shadowlod{number}` entry.
a4	float	Unknown. May be related to LOD distance.
sub_meshes	SubMeshInfo[]	List of submeshes. Addressed by lod infos.
materials	MaterialInfo[]	List of materials used.
bones_to_weight_indices	ushort[]	An array that matches bone indices to weight indices. Any bones not in this list are non-deform.
deform_bone_boundary_box	BBox	Appears to be a boundary box for every deform bone. Not sure what the purpose of this is.
vec4_9	Vec4	Unknown.
a10	Unk_A10	Unknown. Used very rarely in bgXXXX files
vec3_11	Vec3	Unknown.
float12	float	Unknown.
float13	float	Unknown.
float14	float	Unknown.
float15	float	Unknown.
float16	float	Unknown.
float17	float	Unknown.
float18	float	Unknown.
float19	float	Unknown.
float20	float	Unknown.
byte21	byte	Unknown.
byte22	byte	Unknown.
bool23	bool	Unknown.
bool24	bool	Unknown.
bool25	bool	Unknown.
bool26	bool	Unknown.
bool27	bool	Unknown.
bool28	bool	Unknown.
bool29	bool	Unknown.
bool30	bool	Unknown.
bool31	bool	Unknown.
bool32	bool	Unknown.

StreamLOD¶

Contains information on how to read a specific .mmesh, depending on LOD.

Anything polygon related are in terms of polygons times the number of vertices per polygon. As all models are made of tris, these can be thought of as polygon index times 3.

Field Name	Type	Description
mesh_buffers	MeshBufferLocator	Location of each mesh buffer.
chunks	LodChunk[]	Parameters for each lod. Each index corresponds to a `data/model_streaming/lod{number}` entry.
vertex_count	uint	Total of vertices for this lod mesh.
poly_count_x3	uint	The number of polygons (times 3) in the entire .mmesh.
buffer_types	byte	Bitflags determining what mesh buffers are contained in the LOD. 1 = Mesh data (vertex then indices), 2 = Vertex Weight Indices, 8 = Vertex Weights
a6	byte	Unknown.

MeshBufferLocator¶

A .mmesh is broken into different "buffers".

Field Name	Type	Description
offset	uint64	Offset of the buffer within `.mmesh`.
BoundaryBox	BBox	Size of the buffer within `.mmesh`.

LodChunk¶

Field Name	Type	Description
offset	uint	Beginning polygon index (times 3) for the chunk.
count	uint	Number of polygons (times 3) in the chunk.
sub_mesh_id	byte	The index of the submesh the chunk belongs to.
material_id	byte	The index of the material the chunk belongs to.
a5	byte	Unknown.
a6	byte	Unknown.

SubMeshInfo¶

All .minfos are comprised of one or more submeshes. These submeshes can be toggled on and off separately.

Field Name	Type	Description
name	string	Name of the sub mesh.
bbox	BoundaryBox	Boundary box for the sub mesh.

MaterialInfo¶

Contains all material slots.

Field Name	Type	Description
unique_name_hash	XXHash32Custom(str)	Unknown String hash. May need to be unique. Also referenced in a few master.evtb files.
unk_flags	byte	Unknown, likely bitflags.

Unk_A10¶

Field Name	Type	Description
unk_id	XXHash32Custom(str)	Unknown String hash. Not always used.
a2	float	Unknown.
a3	byte	Unknown.
a4	byte	Unknown.
