I agree with Mock (again, I just did that in another thread...). I chickened out and continued to use my ppp for mimic/pose animations then would save and go out and open up my P5 to do production rendering. Since P5sr2.1, been getting gutzy and using P5 - on laptop (yes is legal to install on A laptop and A desktop (confirmed with cl at release 1) I cannot do anything other than a plain draft style render on laptop but everything else works great. Can even use remote control from laptop to run my desktop with P5 and it will render production. Difference? my desktop is 1g mem, p42.8, virmem set to 4096 x 4096 with over 150g free harddrive running xppro in classic mode, laptop is 198m 650 with only 25g harddrive free in win98SE. Now I am even building my characters (non people), made in carrera, in P5 and barely touch PPP. P5 material room is a killer to learn but once you play around with it - WOW. Hair, cloth ok - face room - who cares in my book. So as a final.... I would upgrade to p5 if I were you
