thanks dlk30341 I am not sure to understand what you mean with the procedurals more stable. Could you please develop further? edversyp, I mainly tested Infinite on my laptop, which is a XP Home SP1 system on a Pentium4 2.8 GHz, 1Gb RAM, and an Nvidia GeForce openGL card that experts tell me is made only for the laptops (meaning it's different from the cards they make for the normal computers). I have to admit that I used to have some memory management problem with dense scenes using past versions of Vue 5 esprit on all my computers (which include the aforementioned laptop and two desktop units, one featuring XP Pro on a pentium 4 2.4Ghz and 1GbRAM and Radeon graphic board, another featuring Win2000 on a Pentium 3 800Mhz 750MbRAM and GeForceII graphic board). But I have not tested yet the latest Esprit patch so the problems may have been solved there too. As for Infinite, the fact that the problems are gone on my laptop (and the fact that other testers have reported the great improvements on the memory management side) makes me expect that it will behave well on my desktop unit too :-) And - you all will love the new distribution tool :-) Because it uses an instancing system that does not overcharge the system even with high numbers of replicas. I judge this release of 5 Infinite, the most significant progress in Vue's evolution since the transition form version 3 to version 4.
