MDL

MDL is the extension for Source's proprietary model format. It defines the structure of the model along with animation, bounding box, hit box, material, mesh and LOD information. It does not, however, contain all the information needed for the model. Additional data is stored in PHY, ANI, VTX and VVD files.

Several NPCs also make use of external .mdl files to hold animation data. Usually the NPC classname is appended with a descriptive label, such as:

• _animations.mdl
• _gestures.mdl
• _postures.mdl
• _ss.mdl
• _shared.mdl
