The model tag contains the render model and [shader_model] references for objects such as vehicles, scenery, and weapons among others. It is not collideable nor animated on its own, and objects may reference additional model_collision_geometry and model_animations tags.

This tag is specific to Halo 1 for Xbox, while the gbxmodel tag is the equivalent for the PC port and its derivatives like MCC. Unlike a Gearbox model, this tag's compressed vertices are copied into the map rather than uncompressed vertices. Note that compressed vertices can only address up to 42 nodes.
