"In Vue 4.5 Pro, I ran into some nasty saving crashes when using 10 or so hires Poser figures." well, that is clearly on the limit of the possibilities of today's home computers. It's important to point out that any 3D software, not just Vue, will have serious problems handling 10 high resolution Poser figures. "But by replacing them with a couple of simple untextured boxes I could manipulate the scene fast and fine. Just before the render I replaced those boxes with the Poser figs (saved as VOB)." Yes, that is definitely the way to go when a scene is so much busy. "Render went fine, saving was impossible." Well, as long as you keep the poser figures in a folder together with the Vue scene, and a txt note of what replaces which, you can also save the scene with the placeholders and, in case you need to re-render, just re-replace them with the poser figures. Not ideal, but possible. The best solution IMHO would be to decimate the Poser figures that are distant (if there is any)
