I need to update only the viewable portion of a mesh, since updating the entire mesh is too slow.
I was attempting to do something like
import copy tempMesh = copy.copy(myMesh) myMesh.faces =  myMesh.verts =  faceList, vertList = createSublist(tempMesh) myMesh.faces = faceList myMesh.verts = vertList def doStuff(): ... myMesh.update() ... myMesh = tempMesh myMesh.update()
however copy and deepcopy give me an error.
Can someone suggest and alternative?
