Stripes vs distibute rendering?

[Kr0no]

Hi everyone, I just want to have an idea of wich one is better, stripes or distributed rendering? I tend to beleive that the distribute rendering is more effective as you dont have different GI solution on different machine because they calculate each their own solution, and the overlap is somehow a bit of double calculation and a bit of waste and distribute is seemless for the whole image as they share the same solution and does'nt calculate the overlap, what is your idea, best solution between both? I want to have the opinion of the community please.

I use DR and have been for over 5 years or so. Used stripes a little bit prior to that, but DR just works well. LC is calculated locally and IMap shared. Would be nice if Vray could send the LC calculation to the fastest computer on your network and then share the result, but hey-ho.

Stripes are painful if Max decides to not stitch them together properly which is 99.9% of the time.
DR is simple and works fantastically.

Thanks for sharing your thought, I really think stripes are painful too and distibuted is way more effective.

Anyone else want to share on the subject?

Best regards.

Excuse my ignorance, but I don't understand why you need to hear more. Stripes are crap. DR is great. Isn't that enough?

Heya

It depends on resolution. I would suggest stripes for big res. DBR for small res. The striped are good + even better if you use EXR and so on. I definietly would use it over DBR as it dont stress internet so much and I wont lose all data if my main machine crach. Bit saver option. Depends which stripes btw, Deadline or Backburner?

Also if you use stripes you can send them to amazon render farm quite easy and get all rendered automatically and saved to ur local hdd.

OK - I take my earlier comment back. Stripes clearly aren't necessarily crap.

They not thaaad bad Just need a little bit more maintenance and luck with them They also might be bit saver option just in case 1DBR decided not to load some textures and render black buckets


Edit : To be honest if I were to render on farm Id send stripe as its a lot easier/faster for PC to render and when I test I'd use DBR...

The biggest draw backs ale overlap size(which u can customize) and sometimes not stitching which you can resend so its not that bad. - however there might be more I used it long time ago!

Thanks again for sharing, In a situation where your at the office late at night and need the renders to send to client as soon as they are done, I think the DR is more efficient when you have 30 computer on the render farm availaible and you need to see the render as it calculate to validate if errors slipped in, it s just a quick around and I can get my render and my elements in 5-6 min for 3600*3000 and I need to render 10-12 images.....the stripes in this situation is just a bit of waste with the overlapp calculation, the individual GI solution for the different strippes and the possibilities of render error ( different bucket, different solution that does'nt blend correctly, and the big possibilitie that the render won' t be stitche correctly) and you dont see them render on the fly and can not validate the possible human error of littlte things forgot in the scene as you work overtime and under pressure. In another situation where you have the luxury to wait for your renders and its juste a matter of calculations times ( 600 min timeout by default) I know you can change this timeout but by default 10 hours should be more then enough....And you need other computers to render other job, well maybe the strippes rendering is a good choice, not sure though cuz its been a while I did'nt use the strippes but at sometimes the render element did'nt render correctly but I think its been fix, not sure yet.....I would need to test or if someone can confim it.....my 2 cents

And Tricky thanks for you share and I started this post after a discussion with a collegue and Im just openning up to others ideas, opinions and point of views.

Heya

Good points here and there. 1 - you can check striped renders on the go, just log in on maching and check render. 2 If stiped finish then PC render next image however if u have 30 pcs and 1 pc render DBR and has 2h ETA. Then the rest of 29 computers does nothing for 2h untill the 1 finish render... With striped u'd have all rendered. So if you have 12 images, and each image will have 1-2h lag because of 1 PC than you are looking at 12-24h of rendering on DBR...

Both methods are good and both have their +/-... Pick the right option for the right kind of job

Yeah exactly, you have some good points too, and its always good to see the other side of the medal...
