The Gearbox model tag contains the render models (LODs) 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.

Don't confuse this tag with the Xbox-only model, which Gearbox modified for the PC port. It is therefore used in all derivatives of that port, like Mac, Demo, and MCC. Unlike the Xbox version, the Gearbox model uses uncompressed vertices.

Shaders #

Each "part" of a model can reference a different shader, like the Warthog's windscreen using a transparent shader while its body uses a shader_model. While a model can technically reference any kind of shader, referencing a shader_environment (used for BSPs) is not recommended because the game does not support all of its features and it renders incorrectly in fog in Custom Edition.
