just a miner not. I don't use CPS eather.. the mel script. its as slow as subD's, but it is nice for automaticly seeing a mirror image if your only working on one side.. but even that in low poly can be slow at least on my computer above like 1200 faces (unsmothed).. and that is not really a lot of faces..

so i just make what ever or do the tweeks I have in mind.. thin smoth to inspect the results. undo the smoth and move on..
