gronked one together, attached in case anyone else needs a quick convert :)
mm, always found the unexposed portions of PRC slightly confounding, though I guess its just a different design philosophy..
It's slowing down because, as the Master/Reference file, it holds 10+ quite heavy if individually manageable meshes that, together, become unmanageable.
Was looking for a quick plug'n'play system, but in this case I'll have to settle for a conversion tool I think. Still better than 20+ meshes freezing up gh though >_>
mostly I have to forgo most of the simpler* options as it'd just confuse the end-users (i.e. other people in the practice :P)
