    This is quite fascinating as I had no idea it took so many different people working in different departments to make these shows. It's great that THIS show, at the very least, lets us see behind the curtain a bit and puts faces with names that we may have read in the credits but had no idea what they actually did.

    Really interesting. Would love to hear more from the tech team!

    Amazing work, keep it up, CRWBY! I'm so excited for the episodes and it's also exciting to see what's going on behind the scenes. Looking forward to the future episodes.

    Thank you tech team for your hard work. Someone's gotta build the stuff that the artists work on. You guys make a lot of stuff happen and I'm very appreciative (nobody likes technical difficulties).

    It's episodes like this that help put doing creative work on your own into perspective, as well as how a team can grow. I think before today I just assumed all artists dealt with their own technical issues on their own, it didn't occur to me there'd be another team to work on that. What a beautiful environment to work in. I don't feel so unaccomplished now when I have to learn this all on my own.

      Believe me, we wouldn't be able to work as efficiently as we do without our tech team, so big thanks to them! Plus, they're a great group of people.

      Before I was part of this tech team, I was one of the artists that dealt with the technical issues on my own (which is what lead me here). With a team this size, it's cool to be able to help out my animation peeps and let them do what they do best. They should be animating, not figuring out why software has decided to revolt on a given day and how to get it to behave.

    What type of server boxes do you guys use to package the GPUs, power suppliers, coolant, etc. for your Renderers? Any particular reason why you prefer it?


    Is there a reason why each GPU Renderer is limited to 4 GTX 1080/Ti's in each box? Could you fit more inside each of them or would there be some problems with that? 


    Is there certain parts of the production or show that require CPU rendering over GPU rendering? I'm asking this because it is a fact that GPUs render a lot faster than CPUs so I was wondering if there are certain VFX or other parts of the show that would require the use of CPU rendering over GPU rendering.

      I clearly don't work there, but I imagine that they are limited to 4 GPU's per box because 1. Heat Dissipation, especially in that tight config, 2. Most motherboards only support 2 way multi GPU's so they will need slightly more specialised hardware, including PSU's. 


      I'd imagine CPU rendering is mabye for physics, but GPU's are also good at this. I'm sure CPU's will be used for actual video encoding and compression. The video provided here on the site is very well compressed considering H.264 and the profiles/levels. 


      I was baffled at the 1/2 a petaflop of computation they have in GPU's, but if these are made weekly, that a lot of people sharing the farm rig from Compositors, Special Effects etc.


      This is my outside take. Would love to know more! ;)

      We are using Chenbro cases. They are 4U and are based around consumer hardware, so that keeps the price down a lot. Being able to run to a store locally and grab parts is nice fall back if stuff breaks.


      There are some Server level cases that can support 8-10 GPU's in 5U, but to power them we need more space on the rack for UPS's. I think we ended up getting like 8 more cards per rack when we specced that out, but it was a lot more expensive. 


      Using Blower style cards make cooling the cards really easy, so we could throw a bunch side by side and not have to worry about over heating (provided you have a good amount of intake and a temp controlled room).


      Currently we are using CPU rendering for Pencil+ (Eric mentions it in the video) and a lot of the Comp work is still CPU bound, but things are generally moving to GPU rendering whenever possible. Video encoding is mostly CPU bound as well. VFX is also pretty heavy on the CPU still.  2D shows (Camp Camp, RTAA) are all CPU rendered as well. 


      We won't know till later in the year what our Render needs will be, but I'm pretty confident we're going to be adding at minimum another 16 machines. Once you have the render muscle, the artists want to push what they can do and make things look better or more details, which in turn means we need more hardware. Its a vicious cycle that I very much enjoy. 


      Very excited to see what the GTX line for Volta is going to look like in a few months. Probably going to be swapping in those as soon as we can get a hold of them.

      As @plumpo said you can many more gpu's per but cost starts to scale exponentially with super dense configurations and it is better to just add more clusters.

      @CallumGibson


      Thank you for your input. So they limit themselves to 4 GPU's per box for conservation of heat. That makes sense. Thank you.


      @plumpo


      That was pretty informative. Thank you.


      I got some info you might be interested in. In regards to rendering, I know that in maybe 1-3 years, Pixar will release Renderman XPU, a rendering software intended to use both the CPU and GPU concurrently, taking full advantage of workstation resources. That means your stuff gets rendered even faster. 


      Of RenderMan’s main rivals, Arnold is still purely CPU-based, its much-anticipated GPU support having failed to materialise in Arnold 5 this year; while Redshift is GPU-based, and takes little advantage of the CPU. 


      V-Ray does have a new hybrid CPU/GPU rendering system, rolled out in V-Ray 3.6 for 3ds Max earlier this year, but it’s only for the V-Ray RT interactive renderer, not the production renderer.


      So if Pixar gets it right, they'll be able to help practically every production company in the world use all their hardware resources more efficiently. Of course, whether you guys decide to switch from Redshift to Renderman XPU depends on whether you like the latter's rendering visual product. But I think it's something pretty cool to watch out for.


      --------


      What type of CPU do you think would be needed to complement the Nvidia Titan V?


      -------


      The other thing is about the Nvidia Titan V. I read through a review of the Titan V by Puget Systems:


      https://www.pugetsystems.com/blog/2017/12/12/A-quick-look-at-Titan-V-rendering-performance-1083/


      The Titan V is mainly intended for Deep Learning and Artificial Intelligence but it can also be used to render due to the sheer number of CUDA cores it has. So even if you don't have any real need for any of the Deep Learning/A.I. stuff, you got this. 


      Through a benchmark test that they compared to a GeForce GTX 1080Ti, using the available rendering software that currently work on the Titan V, which are V-Ray and Furryball RT, with Redshift and OctaneRender being available for it in the future.


      Anyways, the results showed that the Titan V was easily 60% faster to the 1080Ti on V-Ray and nearly twice as fast as the 1080Ti on Furryball RT. So 1 Titan V basically equals 2 GTX 1080Ti. 


      However, it's $3000 price tag, which is just a bit over 4 times the price of a GTX 1080Ti so the price is a bit of a problem. Either way, it's still a better deal than getting the workstation class Nvidia Quadro P6000 with its insane price of $5000. Anyways, take a look at the article if you want. 


      Although I'm kind of worried about something. Nvidia recently made an announcement that they were banning the mass buying of GTX 1080Ti's for use in data centers because they were cheaper than the Quadro P600. So would your Renderfarm count as a "data center"? Or at what point in expansion will it be considered one?

    I'd love to see final rendering tech and process at some point. Do you use a CPU server, workstation GPU's?

      We're using Desktop GPUs. Our primary farm has 64 GPUS (32 1080s and 32 1080TI's). CPU Rendering is done mostly on a bunch of 4970k's and some 4770k's.

      Interesting. Wasn't expecting so many GPU's. Any reason why you don't use Quadro's? Edit : 576 TFLOPS with GPU's, that's nuts.

      Quadros/Tesla's are expensive and for the price don't offer the proportional speed for rendering. They give a lot more VRAM, so they can have does much more complex scenes (and we're not there yet).

      The animation looks pretty but it makes the action much slower. They might want to return to motion capture after the poor quality of the fights in volumes 4 and 5.

      ya know, im 18 now, but when i saw the first trailers in like...what? 2012? that litterally inspired me to become an animator, im graduating soon and i was able to take classes in cinematography and animation thankfully from my district, Monty and RT are amazing
