I'm in the process of rendering a large file to disk and have run into some trouble. This file has some volumetric materials and is large enough pixelwise to make the following a reasonable expenditure of time versus just re-rendering... First time I ran it the power went out and I have a half rendered image. Knowing that I can't get Bryce to start where it stopped I tried shrinking the height of the image and repositioning the camera but the two images didn't merge. I could see a difference in angle. So I flipped the camera 180 degrees in an attempt to recreate the problem but this time have the bottom half to salvage and merge with the top. Well, all of a sudden it was daytime in the image. When I flipped the director's view (my primary view for rendering), night turned into day. I managed to proceed with this option but I had to change the scene to a daylight scene in order for it to render as night. :) Just something strange I wanted to pass along. Moral of the story; Uniterruptable Power Supply.

About the rendering. You can actually stop a render, save and then resume with the "dot" next to the "render"...dot.

Not if it's a render to disk operation you can't resume it after you stop.

Aldaron is right, you can't stop and resume a "Render to Disk". Sounds like you should have just restarted the render from the beginning, but I understand how frustrating that can be when you've already let something render overnight.

I didn't just let this render "overnight." It was over three nights. The render size is 5091 by 1831 pixels at 300 dpi. Add in the volumetric materials and it's FUBAR. I'm running a 700 Mhz Athlon into the ground. :) High time for an upgrade.

At that dimension size, you will have to re-render. If it was something simple like, an 800x600 pic, you could up your desktop to 1024x768, make your bryce document window 800x600, give your half-rendered pic the same name as the .br4 file, and up it would come along with the file when you opened it. Then all you would have to do is plop render the missing piece. BUT...at 5091x1831....you be fubar-ed. Have to re-render, sorry. AgentSmith

I don't know if this idea is really relevant, but thought I'd toss it in here... Could you cut the size of the image, and render the scene in parts and reassemble them in post production? Just an idea, don't know it's viability.
