LW - can't render in the highest quality

[Anonymous]

I have a problem with the LW rendering engine. I tried to render a quite large project and there was no problem until I had used the best antialiasing. After this, it computed for a while and then appeared only background image, but no error message. With lower antialiasing level it's OK.
Have anybody experienced anything like this?

PS: Computer configuration - P IV 3,2MHz, 2GB RAM, ATI FireGL 3200, 160 GB SATA

We have had similar issues from nothing rendering to banding in the rendering. It has been suggested by those knowledgable on this subject (not me) that this may be a memory exhaustion type of issue related to Windows XP and it's 32 bit architecture having a 2GB processing limitation as it interacts with Lightworks. Another suggestion linked issues with the video card to the BIOS configuration. For nVidia cards see record #962 in the GSUS Knowledge Base. Macs seem to have less problems in general with this issue. Also please see http://archicad-talk.graphisoft.com/viewtopic.php?t=9119&postdays=0&postorder=desc&&start=10
That's all I know on this topic.

Best antialiasing does take way more memory, if not a lot more time.

Try maintaining best antialiasing while backing off the Rendering Method from Best to Final.

Or you can always render twice that big than you need with "better AA" and resize it after.

Thanks for your help. The project has been more or less successfully finished, so I'm looking forward another problems on my next project. Neither the way with lower method and best AA didn't help, nor the double-size method, because I need the largest format (4048px) anyway.

So, aren't we going to see it?
