Each geometry has a separate description of a model. 

Every model needs a mesh. Meshes are 3D models that represent objects in a virtual environment.

A mesh is a .3ds file (the 3D image format used by Autodesk 3D Studio) or a .gltf/.glb file (the open standard 3D image format).

Meshes are stored in the Meshes pool after they have been imported to the show.

- For more information about importing meshes, see [Meshes](/grandma3/2-4/meshes/).
