Description

An array containing all triangles in the Mesh.

The array is a list of triangles that contains indices into the vertex array. The size of the triangle array must always be a multiple of 3. Vertices can be shared by simply indexing into the same vertex. If the Mesh contains multiple sub-Meshes (Materials), the triangle list will contain all triangles of all submeshes. When you assign a triangle array, the subMeshCount is set to 1. If you want to have multiple sub-Meshes, use subMeshCount and SetTriangles.

It is recommended to assign a triangle array after assigning the vertex array, in order to avoid out of bounds errors.
