It depends on if you use Poser. Vue 4's crowning achievment was the ability to Import Poser .PZ3 files! Allthough Vue's skin quality is'nt quite that of Poser, I think it renders faster. It can certainly do mirrors and metalics better! Vue3 may be able to split it's render jobs between computers, but I think Vue 4 can for sure, allthough it may need Mover4 to do so. = )
