Ok, copied 50gig+ worth of stuff from P7 to P6 runtime. Got some results from Interposer. All I can say for myself is "stay away from anything P7 and C6" It doesn't work with pz3's saved in P7 so I resave in P6. Thanks for your help(but this doesn't apply to DAZ) Jean-Luc PS: the reason my runtime files are in P7 runtime is because if they are in P6, P7 can't find the proper files. P6 has no problem finding the files in external runtimes
