Right now, I am rendering out a 24000x24000 image of the Seal of the President of the United States. It's showing that it is using 667 segments, but only one pass. Is there a limit on segments? Not that it really matters to me, so long as the job gets done, I am just curious.

By the way, I intend to sell the model on TurboSquid. Most all of the ones there are just bitmaps placed on a disk shape. Mine can be rendered at any size you want.

Uh oh, it didn't like something, Crashed and saved a blank image file. Oh well, I know that 12000x12000 works. It takes 177 segments for that.

Isn't LW still limited to 16,000 pixels?
Or am I still thinking in the 32-bit Dark Ages?

I always thought segments were just the manageable chunks that LW could cope with in one pass depending on your machine.

I believe you are completely correct, Iain. It wasn't that long ago this subject came up elsewhere here. I think the solution is to render separate camera regions and composite them together later into the larger image.

Hey Shrox,
look for SplitRender plugin. It's a freebie that splits your scene into 3x3, 4x4 or whatever number of segments and save each segment as a separate scene file, which you then queue on the farm (or one comp). When you have everything rendered start the second part of plugin which then combines chunks into one big image. Saved my buttocks lots of times before.

I've tried splitrender but in the separation you can see the trace of the cut image. You need to look a lot to see it, but it's noticeable for a professionnal printer...

Advanced Camera Rendering by Thomas Mangold is brilliant. You could for example do a 4 frame animation & shift the camera for each of the 4 frames & render over 4 computers, & do it all within LW & LWSN
