Hi Neil, It can also happen when Undo = 0, I usually disable it when working with big objects like plants. I've been working without Undo for days without missing it! In real life there's no undo...
Anyway, don't be alarmed by the odd error message, -Mark Hi Mark > 'cannot allocate ..... bytes' , try to save your project, quit RS, restart and load and try to render again. Is this to do with "undo levels" taking up memory? The restart would not have undo level caches filled so that might be available .... the test might be to simply head into preferences and drop undo levels to none. However, I'm only guessing and have no idea how that works anyway. Neil Cooke
