If neither of these things is possible you will have to take a more tactical approach toward the project, from the number of concept iterations, the level of detail within the scene including polycount and texture complexity, to the overall lighting quality and required amount of illumination. If you are producing the work for a client, make them aware of this and work it into your payment plan, and if they’re not willing or able to up the compensation then if you feel it necessary see if you can gain more time. It’s best to plan from the very beginning if you’re going to need a render farm, or whether you have enough time to spare to dedicate to rendering, this way you can budget around it. Much like good and bad CGI, well-done lighting will likely go unnoticed by the average viewer, but bad use of lighting will quickly be noticeable to the human eye, and risks wrenching the viewer from the all-important suspension of disbelief.īenefits of using a render farm How to plan for a render farm? Because lighting requires a large number of complex calculations to simulate the interaction of photons with objects of varying textures, translucency, and scale, this is very energy-intensive on a single computer, whereas render farms bring power, speed, and sheer scale to the table. The process of multi-bounce lighting brings your scene closer and closer to how light acts within the real world. Using a render farm gives you more time to work on or improve upon any of the stages of the pipeline you and/or your client feel necessary. It’s a sad experience to design a character or environment that you’re sure is going to be blooming awesome, only to realise later on that you simply do not have the time nor processing power to make the final render look as good as it deserves to. Sending long-winded test renders or entire sequences off to a render farm frees up a large chunk of that time. If you’re a creator with a single computer to work with, rendering can eat up hours or days of your time, no matter how carefully you optimize your scene or watch your polycount time that could have been spent refining other aspects of your work. Rendering on a renderfarm vs on a personal workstation How do renderfarms impact your work? 1. Plus, in those 3 hours that you’re waiting for the render to be completed, you can use your own computer to continue working or perhaps to take a break and complete a few quests in Cyberpunk 2077. That’s almost 2 weeks! But if you send your project to a render farm, 100 nodes can render your whole project in just 3 hours. This will take you 300 hours to render if you do it on your own computer. And let’s assume that a frame takes 1 hour to render. You’ll appreciate this better with an example: imagine if you have a 10-second animation running at 30 frames per second. Each individual node can be instructed to render an individual frame, allowing multiple frames to be rendered at the same time. These nodes are controlled by a render management software-think of this program as the render overlord that tells all the nodes what to do. Node is another word for a computer that is part of a host of computers whose sole purpose in life is to render. How do render farms perform this sorcery? No magic is involved, my friend. What usually takes days if you try to render on your own machine can now be completed in just hours. By tapping into the power of render farms, your 3D projects can meet deadlines that are set the next day, the next week, or the next month, not the next generation. How do render farms work?Ī render farm is a huge collection of machines harnessed together to do one thing-render your 3D frames. Reducing the headache rendering brings is where render farms come in they are absolutely invaluable in the 3D animation industry, especially when trying to produce computer-generated imagery that looks like it could exist within our world, on a deadline.
