My only complaints with p5 are the backface issue (yeah, you can use the alternate diffuse materials, but it isn't the same....that is a hack!) Memory consumption for renders is significantly greater than p4, which I suspect to be poor memory manangement, not just the cost of the better renderer The weird geometry problems seen on some items that looked fine in p4. This, to me, is absolutely unreasonable. If it rendered fine in p4, then there is no reason for the problem to show up in p5. Otherwise, I love p5. I use vue, so if the geometry crap shows up, I'll generally use vue for rendering (unless it's clothing, in which case, I'm assuming the p4 renderer will work as well as real PP). Would I buy p6, not sure. If they never attempt to address some of the clear bugs in p5 (like the backface thing, or the ugly geometry), probably not. I waited months before upgrading, and only did so after everyone stopped complaining. Frankly, if they had done a little better with the core renderer, I would have been perfectly happy to pay what I did for the precedural materials and improved library system (though, I always believed that should have been fixed in 4:). And, I would have payed 50 more bucks for a cloth room plugin (that has been really the best part of the whole buy). The face room....huge waste of CL resources....at least for me. eric
