AutoCAD Architecture

[#1]

I have a small project where the model is around 1Mb. Renders fine in 2011 at low res, and takes around 10 minutes (same as 2009). But when I crank it up to 4000x2800 it takes about 8 hours to get through the final gather, then crashes. I've rendered the same file in 2009 at the high res in 2 hours, no problems, so there's nothing wrong with the file.
At first it crashed after 4 hours in 2011, then I increased the RAM allocation in the Rpref palette to 6Gb and it crashed after 8 hours. This is a really small file and it shouldn't take so long or be such a drama to get a high res image.

Hardware - 2xdual xeon 2.33Mhz, Win XP64 SP2, 8 Gb RAM, Nvidia quadro FX1500 with certified driver. Loads of free spae on the hard drive, 2Gb page file.

Well, that's less than thrilling news! Should we expect that fix in Update 2, or ACA 2012? I was just planning to install 2011 today, but not so excited now!

Honestly, without a CAD file from the OP and testing by others of the
reported problem, and possible solutions or a real bug-report, you might
want to re-think that.

Simply posting here with no detail or backup does not trigger any bug-fix at
autodesk for any product.

I tried Dean, but the resulting zip file is too big to post. I even tried in the 'customer file (attachments)' but was told it's too big. Interestingly the ground floor file is around 700k and the upper floor is 200k, but when I bind the upper floor for etransmittal the cad file is 1.4Mb. The textures then bring it up to 4Mb, let alone the RPCs (which I don't think I'm allowed to distribute).
I was hoping someone from Adesk would read the post and give me an email address to send it to. Attached is the resulting image. ACA doesn't crash itself, just the render engine, which still reports it is xx% through processing. I can save the file off as-is and Task manager also tells me the CPUs aren't being used.

Are you on subscription? If so are you not able to log something in the sub members site?

Thanks

Jay, have you tried rendering in 2011 at high res? I'd like to optomistically think I'm just doing something wrong.
I've tried the subscription site, but they don't even have my 2011 listed there so I can't register the problem. Had the licence registered for a week and a half. Also, there's no option to upload a file, so it is of no use. I also note (with humour) that I posted an issue on the 3rd of May 2008 about tripple sliding doors. That issue is still open.

Hi,
It would be great if you would send me a simplified dataset. We will look into that.
Thank you for your time and report.

I have the same problem with similar system specs. Low res ok, hi res gives up during final gather. My scene is just an exterior with sun&sky illumination only. I had this trouble with 2010, too, but I attributed it to lack of RAM. Now I'm on 2011 with 8GB and I should be good to go. Good luck working with Adesk. Next option I could try is to render separate regions and then assemble.

I sent them the file and textures a couple of days ago. No word back yet.

Hi,
It does not seem to work work well when using materials with high resolution. Currently the workaround, which you might have already known, is to use lower resolution such as 1024x768. (James has kindly explained to me in a separate email that the high resolution is needed for his works). For other, does the lower resolution meet your business need?) If not would you please give me an example or two when/why you will need that?
Thanks,
Sam
