not concerned about the p4 render engine pwr se but still use some of the p4 figures for filler or background. if i don't use weight mapped figures will the older stuff still work?

will the two versions work efficiently on my macbook pro running os 10.6.8 in 32 or 64 bit?

so damn confusing! and why should i care about any of these.

IDL?  SSS?  iirc?  ibl?  ado?

firefly i guess i already use in the p7 render engine and i know it to be much better than what p4 i used. remember never went throguh allt hose other versions of poser. from p4 to p7 was drasticand i still have no idea what half or more of the p7 stuff is. so going to p9 or p10 gives me the chills. you know, the chills that plague old, brain dead technophobes!
