| triangles | The list of indices that define the triangles. |
| submesh | The submesh to modify. |
| calculateBounds | Calculate the bounding box of the Mesh after setting the triangles. This is done by default. Use false when you want to use the existing bounding box and reduce the CPU cost of setting the triangles. |
Sets the triangle list for the sub-Mesh.
A sub-Mesh is simply a separate triangle list. When the Mesh Renderer uses multiple Materials, you should
ensure that there are as many sub-Meshes as Materials.
It is recommended to assign the triangle array after assigning the vertex array, in order to avoid out-of-bounds errors.
