public bool isReadable ;



Making a mesh readable will keep two copies of it in memory, one for rendering and one in system memory for script access. Setting isReadable to false therefore saves memory. Scaling a mesh with different amounts along the three axes (i.e. non-uniform scaling) requires the mesh to be readable for correct lighting.
