erosiaart, you'll need to make sure the maximum vertical resolution isn;t karger than the bryce window itself. In the document settings sindow, try putting in 700 instead of 867 and ley bryce compute the new horizontal value. See if this fits. What is your screen resolution? 867 pixels high will only work if you have at least 1024 pixels of vertical res, like 1280x1024 or 1600x1050. If you can work horizontally, or have a monitor you can rotate, do that, as you'll have a lot more area to work with on the longer dimension. Also, if you just do a normal bryce render by hitting the button, then stop it when you want, grab the pan tool with the render on-screen and it pans across the render, not within the scene, so you can see the full area. here's a practically perspective-free empty scene: Download Here for bryce 5 this is with the camera FOV at 1 degree and it's very far away and very zoomed in. You can adjust the aspect ratio of the canvas but use the gizmo i've included for manipulating the camera because if you use bryce's controls it will jump around and freak out. I'ce saved the default view in the upper left so if you really mess up just hit the button and it'll bring you back to the center.
