Step-by-Step Tutorial: UE Setup for LED Wall Virtual Production - nDisplay & Switchboard

[@CesarSoto-mx8br]

Ian, thank you so much for this video with Unreal 5. We finally got our setup working in 5.3 with this vid.

[@vptoolkit]

Hey Cesar! So glad to hear you're up and running. Let us know if there is anything else we can do to help!

[@ChrisGeden]

Dude, you need more subs for this great explainer. You’ve gained one more. Thanks.

[@vptoolkit]

Thanks Chris, appreciate your kind words!

What is the Fill DDC (prepare shaders) in switchboard tools menu? There is not a single documentation on that! does it automatically compile shaders on render nodes without having to open each level on them once?

Big thanks!!!

Thanks for the tutorial! Great to watch and learn from. Could I just confirm that in your case, you're sharing the project files on a NAS that each machine is able to access? That's what it sounded like. But I've heard from others that UE doesn't like Network storage locations?

[@vptoolkit]

Hey James, thanks for reaching out! In this video we are using a single nas and one copy of the unreal project. Unreal/ndisplay can run like this for smaller setups but you have to do some workarounds for saving (we go through this in the video a bit) we have also released a video on more complex server workflow where we open up a shared folder on each machine and keep them synchronized using free file sync. Here is a video showing that workflow: kzbin.info/www/bejne/qqTdlYihpt1orq8si=7yjXRCR_GPm21dht hope that helps!

i wonder do you have a very basic beginner tutorial covering eqptmnt needed and is there a way to start to use a tv instead of led wall for cost sake

[@vptoolkit]

Not yet, but we got lots of new tutorials coming to our channel soon! Regarding your question: Yes you can definitely use a TV to get started learning and working with ICVFX virtual production. There are some factors you will be have to into consideration like the fact that TV’s can not be genlocked (synchronized with camera) and most TV’s have reflective surfaces that will show lighting or props on your background. We often use TVs and projectors for demonstration and testing setups with these limitations in mind. Let us know if there is anything else we can do to help!

I work at a nightclub that has a video wall that curves up to the ceiling and also has some panels on the right wall. Is there a way to setup a video render that I can move a camera through a scene and have it record video that can be displayed on the screens. I want to make visual clips of things that fit this strange shape.

How do I use one primary computer and use other internal computers' gpu to render different viewport? I have been dying to search for an answer...

[@vptoolkit]

Hey Thanks for commenting! This is kind of a tough one to answer. There are a few methods to do this, the newest and most current method is to use Multi-Processing. In Feb we are planning to generate some new video content and an updated online course that covers all of these methods in detail but until then I will share you a link for the documentation. Hope this Helps!: dev.epicgames.com/community/learning/courses/ev7/unreal-engine-multi-process-rendering/PpWX/unreal-engine-multi-process-rendering-getting-started

@@vptoolkit Hi, thanks for replying. And yes I read this doc before. Currently I would like to do a test: I have two laptops and they are in the same network, I can set up multi user and ndisplay sessions for each of them. When I launched cluster nodes on switchboard, both of the laptops were rendering out assigned viewport in ndisplay config, which was confusing. I totally understand that ndisplay is a solution for LED screens, but is it possible that I can move rendered node on my secondary laptop to my primary one? So that it is more like a render farm that I do not need to run to different laptops back and forth, and I can use their GPUs to render different viewport of my scene. What is more, I am also wondering what is the differences between running switchboard and previewing in the editor. Even though I set up different hosts inside NDC, when I drag it into the scene and turn on realtime on preview settings, Both viewport still get rendered out. I assume the viewport belongs to other host should not be rendered out or is it shall only be separated rendered out WHILE ndisplay nodes are started in switchboard? If so, inside the editor I am using one laptop's GPU to do a render job that should be assigned to different machines? Thanks for any help, this is confusing me for a long time, I do not know what to do next.

@@chah1653 So I think this might be deeper than a KZbin comment response! There are many ways nDisplay can be configured with multiple machines over a network but I’d have to get some more info on exactly what you’re trying to do to give you a proper answer. We offer hourly consulting if this is something you’d like to setup a time and go over your setup. As for the ndisplay Preview in Editor… That is just rendered on whatever machine you’re running the editor and does not use any performance in an ndisplay instance of UE. The Preview isn’t a true representation of what you will see in your nDisplay projection but it can give a good idea. In a lot of cases we turn it off so that the editor preforms better when making environment changes. We also sometimes turn up the quality if we are testing an environment for how it’ll preform in nDisplay as it kind of “bottle necks” the performance of the project. - Ian

@@vptoolkit Thank you so much for the reply! I now have better understanding of how ndisplay works inside unreal and in switchboard.
