<brief_description>
+ A [Resource] that contains vertex array-based geometry during the import process.
</brief_description>
<description>
+ EditorSceneImporterMesh is a type of [Resource] analogous to [ArrayMesh]. It contains vertex array-based geometry, divided in [i]surfaces[/i]. Each surface contains a completely separate array and a material used to draw it. Design wise, a mesh with multiple surfaces is preferred to a single surface, because objects created in 3D editing software commonly contain multiple materials.
+
+ Unlike its runtime counterpart, [EditorSceneImporterMesh] contains mesh data before various import steps, such as lod and shadow mesh generation, have taken place. Modify surface data by calling [method clear], followed by [method add_surface] for each surface.

<description>
+ Creates a new surface, analogous to [method ArrayMesh.add_surface_from_arrays].
+ Surfaces are created to be rendered using a [code]primitive[/code], which may be any of the types defined in [enum Mesh.PrimitiveType]. (As a note, when using indices, it is recommended to only use points, lines, or triangles.) [method Mesh.get_surface_count] will become the [code]surf_idx[/code] for this new surface.
+ The [code]arrays[/code] argument is an array of arrays. See [enum Mesh.ArrayType] for the values used in this array. For example, [code]arrays[0][/code] is the array of vertices. That first vertex sub-array is always required; the others are optional. Adding an index array puts this function into "index mode" where the vertex and other arrays become the sources of data and the index array defines the vertex order. All sub-arrays must have the same length as the vertex array or be empty, except for [constant Mesh.ARRAY_INDEX] if it is used.
