Project called shopjacket, helps run down high street stores rather then them sitting with empty windows, we add a huge interior render and put it behind the window, give the sign a lick of paint and walla, but we need high quality rendered images,

Need a 5000m x 2500m image at 150 dpi. i mean i could use something like artlantis.... but ... well less said about artlantis the better.

just worried about the lighting and stuff, i mean we've got a few guys at the office who are real good at photoshop so shouldn't be a problem joining em, but the lights diffusion worries me.

What does the "m" stand for?

woops sorry was supposed to type 5000mmx2500mm, its been a long a day.

Add super sampling and you in ~14 Gb of memory use + scene with textures. When this will be possible with GPU rendering?

in about one month from now, using an upcoming cooperation with a 3rd party.
it involves the new fermi 48bit memory model tesla systems/cards.

unfortunately i can't give any specifics about it yet.

Now your your just teasing us
As long its affordable for us mere mortals I'll be happy.

Hello everyone,

I just bought my license - the demo version worked like a charm for me, and with a 280 gtx it's 'quite' fast - I still have to get used to that output quality and speed. Quite amazing, actually: seeing I started on an Amiga 1000 with 512mb(!) and Sculpt Animate 4d. Even line renders could take minutes!

Anyways, in response to the above question about higher resolutions: I tinkered around a bit, and here's a trick that might not be so obvious (with obvious caveats):

- in the camera settings set the position to float3hemi
- zoom into the scene
- render different positions, with portions that overlap (1/3 works well)
- open all renders in Photoshop, and use the Automate-->PhotoMerge function to generate a larger picture.

Obviously, there are a couple of problems with this approach: it is only feasible for certain situations, such as interior renders, or complete exterior environments; the central viewpoint has its disadvantages; perspective distortion; etc. Not at all perfect, but this could be an option for some, and will yield at least twice a higher resolution.

That would be 7GB of video card memory, your system memory will not help in this situation. I haven't heard of a video card from nVidia that has that much memory (7 GB+), even the new Fermi Tesla cards will only go up to 6 GBs of memory last I heard. I think you are out of luck unless something changes, either the Tesla cards come out with more memory, or Radiance changes Octane to allow the rendering size you need.

can't you ty up with some company for increasing RAM on gtx 480s ??
