In Bryce, if I choose an image size that is too big for me to see it all at once on the screen, how can I move it around so I can see this or that part of it? In most other graphics packages there are scroll bars along the right and/or bottom edges of the image display if it is too wide and/or tall for the screen, but not in Bryce.

Yes I'd be interested in hearing this too. That's why most of my renders are the same size , width wise , because it barely fits inside the workspace.

There's no "real way" to do this, however what I will usually do is start an image at a size that fits in the main window, do my image, then size it up before I do my final render keeping the aspect ratio the same will not effect your scene, in other words If I start at the default canvas size and then size it up for a final render, nothing is lost or added. You can also stop a render in progress and while the partial render is up on the screen use command and the + or - keys to zoom out and then hit resume render to see it all render out. On a PC I think it's alt and the + or - keys to zoom it in or out.

Also, on the section where the Zoom buttons are (lower right hand corner) is a hand that you use to drag the screen around. Before you do this, if the camera/view is where you want it, use one of the saved view buttons (don't remember what they're actually called ... :P :) to the left of the nanopreview window. That way, once you get everything set to where you want it, then you can go back. Also, the x-z, x-y, y-z movement controls right above the trackball will do the trick as well.

If I want a larger size I do my scene, then click on document setup and change the size. I recheck the scene as I can to tweak anything the size change affected then render

heya...I'm going to get real technical here. If the scene I am doing is too big for me to see all of it in my sceen I just use the arrow things near the ball thing on the left hand side of the Bryce work screen. The cross shapped arrow thing moves things in and out as well as side to side. The other arrow thing above it on the right moves the pic up and down and side to side...the one on the left moves things in and out as well as up/out and down/in. Also the little dots below the ballthing/camera tracker thing ...right is camera in and out and the left is camera roll.If you just open a new scene and creat a sphere as a reference point and play with them you can find how best to move you scene...which is hand when you have a huge scene that is making your computer groan in protest :) I'm not being a smart arse I'm just not too up on the technical jargon for thses functions so I used the words I use myself :)Hope it helps.

Moving the cameras is one thing. Seeing this or that part of the image display area is another thing.

Okies...it's just I find that moving the camera and using the menu near the namo render handy as it gives me virtually veiws from all sides...although if there is something between me and the part I want to look at it(like a mountain)I select the part I want and take it into the isolation screen by using the menu at the bottom of the screen by clicking on the wireframe sphere to the right.
