The problem i have is around declaring a mesh, I can only do that on the main thread which means I have to have 2 copies of my data ... 1 vertex array when calculating then that gets copied in to another when I create the mesh object, something so simple should be possible on another thread but isn't because the declaration of a mesh is seemingly treated as part of the unity API and thus not threadsafe. Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable.
