Maximum Render Size?
-
Hi,
Just tried rendering the Charlie_V test file.
The best I could get was 7000px with AA switched off.I loaded up my original file which is a lot more complicated and was only able to get 4000px wide (also, I have shadows disabled). So, there does seem to be a number of factors at work here.
However, it seems stange that we are getting a variety of results from different people with machine specs similar to each other.
I rendered JPEG images using Vray and had no problem producing large files.
But as mentioned previously, Vray can write the image to disk rather than hold everything in RAM.Any other thoughts?

I wonder if maybe the working environment has something to do with the export results too. At work, in a networked environment, I get different results than at home. Writing big images to a network folder often fails, or I get corrupt files, and exporting to the desktop works better. These problems happen only with rel. 6, not with v.4. Version 4 and older only have the AA issue, maxing at about 3000 pixels wide with AA on.

Hi Mr S, hi folks.
For a JPG export with anti aliasing off, I can go as far as 7493 horizontal pixels (6636 vertical) with Windows XP-Pro on Pentium 4, 2.6 GHz, 2 Gigs RAM.
I will try on my Mac at home to get a comparison.
Just ideas.

I always have the same problem with exporting images larger than 3000 wide. Given the model is quite complex, about 60MB. SU5 works sometimes. SU6 is worse. My computer isn't a sewing machine either, a quad-core with 4GB of RAM and a QuadroFX 3500, running XP64.

Hey all,
Thanks to all those that gave it a go, and any who have not, please continue.
Given the small sampling of participants & simple file....Results are more or less as expected.(for me anyway).....Varied, and it appears not hardware specific.
I am no programmer....just curious.
Best,

Dejavu....I remember posting on an earlier thread dealing with this same issue, along with the Google folks who informed us they were looking into the problem.
I played around with a simple model on both SU Pro versions 5 and 6. The maximum image I've been able to export is 4000 pixels wide, AA on, jpeg quality at it's highest. However, changing my virtual memory from 2000/10000 MB to 5000/10000 MB I was able to export an image at 5000 pixels with AA on, and 7000 with AA off. Bumping my virtual memory up to 9000/20000 MB I was able to export an image at 9000 pixels with AA off.

Thanks for the input Daniel - that seems to do the trick.

Daniel,
Thanks for the advice on the pagefile limit increase, which did help some.& much apreciated!But........and always a but......right.
On both my Laptop & Desktop I am limited to 4096 max. pagefile.
Given both machines are a few years old(2gig ram)....& not overly computer savvy......why is SU quick to use "vitual"/pagefile memory for such a task?BTW Daniel......this question is not directed @ you...... just me thinking aloud.
Best,
Charlie

I can not export the image JPEG larger than 6000x4000. (uncheck AA) My computer is
AthlonX2 4400+
RAM 2 Gb
GeForce 7300GT -
Daniel,
What do you recomend for pagefile size for a dual core 2.8, 2mg ram, XP?
On some website I found last night, they suggested pf=1.5Xram.
Thank you,

First off, let me make it clear I am not a computer whiz. What I know about virtual memory is that it is used for "tricking" a program that a block of contiguous working memory is available for it's use, and I assume (but not entirely sure) available virtual memory is related to your RAM.
Glenn, the suggestion of 1.5xRAM is probably okay for most applications. When you access the virtual memory window on your computer it will inform you what is available. If needed, you can set it to the max in order to export a larger jpeg, and reset it back at a lower setting when done.
Virtual memory is not the only factor affecting this problem, I am sure. There is also your graphics card, processor, and probably even RAM.
At work I have Pentium 4 3GHz, 1GB of Ram, and NVIDIA 4200 series graphics card and it does okay. At home I have Pentium 4 3GHz, 3GB of Ram, and NVIDIA 6600 series graphics card and is a big improvement (large models I end up working on at home). I recently tried SU on my dad's laptop with VISTA, IGB RAM, and no dedicated graphics card - it wasn't a pleasant experience
. I just ordered a laptop with XP Pro, 4Gb of Ram and NVIDIA 8800 series card...can't wait to see how it performs.Charlie, SU (and other programs) are 'quick' to use virtual memory simply because said programs are memory intensive. If your computers are two years old you might want to look into upgrading their graphics cards and/or RAM. Like I said, I am not a computer whiz, but I do know from experience those things make a difference. Unfortunately, it isn't very long before computers become somewhat obsolete.

Interestg to find this thread just as we were facing a similar prob w/ a large file. Followg Daniel's advice resetting virtual memory worked great to 3000 w/ AA for a 282mb file. Funny thg is that on a hunch I tested the idea on another prob we were havg.
Not sure if Brad is watchg this thread, but as he knows we were unable to save a very large proj file (275mb) w/o a crash, but were able to successfully save a larger file at 311mb all on the same computers. Our files are const models with hundreds of obj and multi layers and TIG Xrefs so it was tough to fig out what was going on. Especially since the crash was occurring at abt 22min into a 35min save, so we gave up. But I just tried the same save for the same file that wouldn't save but w/ virt mem reset at 20,000 and it worked.
Daniel you inadvertently solved a big prob for us, thx very much. And Brad, that might help whatever you all do there irong out that kink....
Thx again
/Dennis
