Bloodsong, I would seriously think about rendering to screen. You can set the dimensions to up to 1600x1200. Bigger than that I cannot go because that is the biggest screen resolution my graphics card will go, and it objects to using a bigger size than that on screen and insists on render to disc for anything bigger. But I rarely render that big anyway. But if you can render to screen you can see all the time what is going on. If you select a render area, and you have the full render size set to, say, 800x600, it will render that selected area only, but it will set it to 800 wide and adjust the depth to keep the proportions, so unless you use the whole width for a render patch, it is not going to be the right size to fit your original. Stopping and resuming rendering works fine with render to screen, but only if you save both the render and the vue file at the point where you stopped rendering. The vue file has info on where it has got to in the render. So if you only save the image and not the vue file, it does not know where to restart the render and gives you an error message. If you save the vue file and not the half finished render (which you cannot do with render to disk because the render is being saved as you go along) then it knows where to start but does not have an image to resume with. If you are getting errors with render to disk, it sounds as though you are not saving the vue file when you stop the render. Be careful when you stop it not to hit ESC twice so it says finished. You will not be able to resume unless you do the saving while it says Stopped. Changing the filename of a half finished render, or resuming under another name would be pretty fatal I would think. It expects to resume the same render that it left off. If you have a pressing need to change filenames, I would do it with Windows Explorer by copying the file to another folder and renaming that, leaving the original unchanged and in the folder where you saved it from the render option. If you are trying to do something else while rendering, usually it will be the something else that suffers, not Vue. Vue simply takes over the resources and leaves everything else to struggle. I hope some of this helps.
