View Full Version : Who has the longest single frame render time?

I use Lightwave for illustration and I have always wondered… what is the longest someone will wait for a single frame render. When you look at big bit HDR image based lighting, high level radiosity (to keep the specs of the HDRI lighing down), caustics and depth blur (to name a few). Your times can get insane and more so if you render at print resolutions.

So my question is what is the longest users have waited for a single render? I guess answers could be in actual hours for older machines or ghz hours for multi CPU's or farm renders (whatever is easiest).

The longest I have waited was about 5 days but that was 6 or 7 years ago. I could probably re-render that in about 10 minutes now (lol).

I waited two days for a render once. That was about 5 years ago though. Now days it's pretty typical if I am rendering for print to have it take about 8 hours. Anything longer than that and I try really hard to tweak the scene in order to speed it up. I am an impatient person.

i typically cancel a really long render if it doesnt get to a certain point in a given amount of time and make tweaks and shortcuts in order to reduce the time to an acceptable level. render in segments, etc. its a never ending game of ballance. im sure if i let some of the renders go they would go on for days though, but most deadlines dont let me do that.

24 days on amiga500 with real3d 1.3
I think it was the teapot scene with a lot of bump

Hmmm...i think when using MR i might have had a render that would have taken, oh, i don't know, till the processor probably would have worn down from old age, had i not stopped it (mind you, that is normal sometimes for MR and Maya)

As for LW, i think couple of hours for a frame, i do animation and VFX work, and budgets and deadlines are too tight to go above anywhere from 1 to 2 hours a frame.

I've waited 3 days for just a boolean to take place
and also 4 days per frame for a 100 frame anim

All on the Amiga 4000 (and even it had the super-duper 040 warp engine and 128 megs ram)

And that was fast then

About 300 hours, back in the day.

Looked like crap.

These days, if it's over about half an hour a frame, I cheat by pre-processing bits and pieces.

27 days and a bit for one Povray scene... 4000x3000 with every option turned on, tons of refraction...

9 years - I'm still waiting for the window frame at the front of my house to be rendered - looks like poo at the moment.

Wow! You waited 400 days to see a 3 second animation! :thumbsup:

Hope you didn't have to change anything. :D

Eee, back when we had to send to NewTek for jiffy-bags of fresh pixels every week, and this one week they ran out of blue pixels so we had to render everything in shades of brown and orange. Back when we had to cut raw polygons out of the code-face ourselves, din't have none o'these fancy subdiv thingies...

3-4 hours is the longest I'll wait for a render. If it doesn't look like it will pass the "patience test," I'll stop the render and make some shortcuts.

On Respower I once waited 3 days with 10xPCs working on a single print resolution render

Rendered a human head with imagine 4 on a 133Mhz pc which took about 24 hrs, zippy compared to some of the above, that was about 12 years ago.

These days I'll go to around 15 minutes per frame of animation before taking the compositing route.

You should try them on a public holiday. I had 600+ machines all blazing away at one of my scenes.

I've never been quite the same since.

Nope just playin around, Had a toaster 3000 also and just bought the newest
286 PC and was playin with that too, so I let the 4000 warp engine run it's course.
And it's still going after all these years without shutting down unless I turn it off...wish the 3000 was the same :)

Two bounces of monte carlo radiosity and three area lights made me wait about 30-40 hours once. I accidentally screwed up my Kray settings once, and it took something similar. ****ed global illumination!

5 days to get this TAG watch image (http://archeidos.com/images/watch/finals/1000x667.jpg) be 10,000x6667 pixels.

For animation, 200 hours for this animation (http://www.archeidos.com/videos/sexandthesocket/final/sorensor/sorensor.html)

Both using a BOXX dual 3.4 intel processor and using FPrime to render
