Right, geoegress, but it's not the DPI that's crashing the system, it's the pixel resolution (4000x4000). Again, the DPI has no effect on anything except when printing. All that value does is tell the printing program how many pixels will fit into an inch on a printed page. Try changing the DPI in Photoshop (or whatever image app) to 72dpi while retaining the 4000x4000 pixel resolution. Then watch Poser still crash. ;) Rendering at 300dpi is good if you intend to print the rendered image on a printer that does 300dpi (or better). But try this: 1. Render at 640x480@300dpi, save. 2. Render at 640x480@150dpi, save with different name. 3. Load both into Photoshop (et al) and see the difference in print coverage (File->Print Options...) on a standard sheet (8.5x11"). Both images have the exact same number of pixels, 640x480, and are the same size in pixels and filesize, aren't they? But they print with different sizes. That's what the DPI value is used for.
