<brief_description>
Node for 3D tile-based maps.
</brief_description>
<description>
GridMap lets you place meshes on a grid interactively. It works both from the editor and can help you create in-game level editors.
GridMaps use a [MeshLibrary] which contain a list of tiles: meshes with materials plus optional collisions and extra elements.
A GridMap contains a collection of cells. Each grid cell refers to a [MeshLibrary] item. All cells in the map have the same dimensions.
A GridMap is split into a sparse collection of octants for efficient rendering and physics processing. Every octant has the same dimensions and can contain several cells.
