| 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. |
| baseVertex | Optional vertex offset that is added to all triangle vertex indices. |
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.
The baseVertex argument can be used to achieve meshes that are larger than 65535 vertices while using 16 bit index buffers,
as long as each submesh fits within its own 65535 vertex area. For example, if the index buffer that is passed to SetTriangles
contains indices 10,11,12 and baseVertex is set to 100000, then effectively vertices 100010, 100011 and 100012 will be
used for rendering.
