First: welcome to the Bryceaholic Anonymous :) Second: Bryce works mainly with BMP (if you have a PC) and PICT (if you use a Mac). The resolution of the rendered image is the one you choose in the Document Setup and/or in the Render Options pop-up. I recommend you to go to the Edit-->Preferences menu and choose "Image wiht Scene Open/Save" (see screenshot above). Doing so, you'll have your image named after your scenefile and you'll be able to stop/resume a render anytime. Third: You can then set the different desired resolution, and JPEG compression, in every photo-editing software later. Take into account that it's almost always better working *reducing* the res instead of the opposite. So, for example, it's better to render at 1024 and then downsampling to 800 than vice-versa. Fourth: Happy Brycing... --- Stefano
