DontRecalculateBounds = 8

Remarks

When you use Mesh.SetSubMesh to modify a Mesh's data, Unity's default behaviour is to re-calculate the values of the SubMeshDescriptor.bounds, startVertex and SubMeshDescriptor.vertexCount fields from the current vertex and index buffer data.
You can make Unity skip these calculations by using the /MeshUpdateFlags.DontRecalculateBounds/ flag. This can be beneficial to performance, however if you use this flag you must make sure that you pass correct values of the 
bounds
, 
startVertex
and 
vertexCount
fields.
