[[Hardware instancing]] is a technique which allows the GPU to render multiple identical meshes in a single [[draw call]], varying a limited amount of state (such as position and orientation) for each mesh. This is used to reduce the cost of drawing a moderate number of identical low-to-mid-detail meshes. Where [[mesh stitching]] is possible, it is currently used in preference to hardware instancing. Strictly speaking, instancing is performed per [[render chunk]] rather than per mesh.

Cases where hardware instancing is possible and mesh stitching is not possible include:
* Meshes attached to moving or animated parents, such as sub-meshes attached to a Train Vehicle.
* [[Render chunks]] which exceed the maximum vertex or index counts (currently 3000 of either).

Cases where hardware instancing is not supported include:
* Meshes which are subject to software-controlled manipulation (such as track splines).
* Meshes with [[skeleton]]s.
