I've only recently figured out the multi runtimes and am so happy now. I hated hunting through all the v stuff trying to find mikes ~G~ I suppose I could have broke it down more, but what I did is. Mike 2 and 3 have their own, everything related to them is in there. V2 and 3 the same, Koshi as well. Hair goes into the main, props into download. So far I've had no problems. My pzz files export easily into Vue etc.
