Alekssander, it happend to me quite often that Vue did not even let me save my work. A popup with just Vue d'Esprit and OK in and nothing more, no error message, no explanation. The computer freezes. And I have less of half of the power of your 'puter. That's why, when a scene becomes to be very heavy, I do the following (ALL OF THEM): 1. Shut down ALL resident programs, except EXPLORER and SYSTRAY in doing Ctrl+Alt+Del for each one before opening Vue. 2. In Vue I group all objects that can be grouped. 3. I HIDE every object and Layers that I have not to see absolutely 4. I disable OPENGL (needs to restart Vue) 5. I close my internet connection (normally always on) and stop my webcam, of course. 6. While working in Vue, I open sometimes "Rsrcmtr.exe" from the Window folder to see how much memory I have available to work with and close it immiately after because it also takes memory. 7. While working in Vue I save my work after each 2 or 3 changings in my scene as scene1.vue the first time, as scene2.vue the second time and as scene3.vue the third time. Then starting again for the fourth time to save as scene1.vue and so fort. If ever there is a problem, I always have a recent save from my scene. And believe me, I have scenes they need 12 minutes to save (my latest forest image is just such a sample, there are about 100 real trees and lots of other plants in, as well as lots of fog.) 8. And last, but not least, when I feel Vue becomes very slow, I save and restart my computer. All these things are very constraining, but what wouldn't I do for my love Vue? (LOL) Guitta
