MSH Meshes

MSH — Meshes

Extension

.msh

Purpose

MSH files contain 3D mesh data used by Getting Up game assets.

They are mainly used for:

• Characters
• Props
• Objects
• Vehicles
• Environment scenery

Tool support

Getting Up Modding Tool currently supports:

• Reading MSH files
• 3D preview
• Mesh inspection
• Export

Mesh information

Depending on the resource, mesh data may include:

• Geometry
• Mesh sections
• Materials references
• UV coordinates
• Skeleton data for skinned meshes

Related resources

MSH files can interact with other game formats:

• .st — Texture resources
• .mtm — Material resources
• .bnm — Animation resources
• .gat — Attachment information

These resources may be required together to reproduce the complete in-game asset.

Export formats

Supported meshes can be exported to:

• OBJ
• glTF 2.0
• GLB

See Export Overview.

Reverse-engineering notes

Document discovered binary fields here as they become confirmed.

Recommended structure:

1. Header
2. Section table
3. Vertex data
4. Index data
5. Material references
6. UV data
7. Skeleton / skinning data
8. Attachment information
9. Unknown fields

Unknown areas

Some MSH fields may still require further investigation.

Keep a clear distinction between:

• Confirmed behavior
• Observed patterns
• Current hypotheses
• Unknown fields
