In the last 2 months I have asked a lot of questions on this forum but I'm new to Vue and the advice/tips I have received have been invaluable - thanks. I've got another question about rendering. I am trying to produce high resolution renders in Vue Infinite - these will finally be outputed as large scale 30ft x 9ft size prints to be shown in a gallery so I'm trying to get as high reslotion as possible so the images will be as detailed as possible close-up. I will be refining this with post-work in photoshop. I'm using a dual 2.5 powwerpc G5 Mac with 4.5 GBSDRAM. Unfortunately I just had a 46 hour render crash as it was writing the final file and I've lost it. I can't afford to have this happen too many more times so I'm trying to get a few things worked out. Sorry if some of this is obvious but any answers/suggestions of tutorials would be appreciated. 1] I now realise I should have regularly saved the render. Do I do this by stopping the render (press esc) then saving (File/save as) 'render1', 'render2' etc? 2] When I stop the render is there anything I can do before I restart the render to optimise the computer? 3] Is the standalone renderer a more efficient way of rendering than normal render to disk (obviously render to screen is not an option). How can I optimise this method? 4] Would adding more RAM to my computer help? 5] Would connecting up a Mac powerbook as a render cow help? 6] I am also thinking of using Pete;'s idea of tile rendering - http://www.petes-oasis.com/tilerendering. Has anyone used this with Vue 6 infinite? Thanks again John
