It crashes a lot, but at least ot works! I did a quick test on a marketplace scene for comparisong, using Nanite only. Weird thing is that the scene without Lumen nor Nanite is running at 13ms, while enabling Nanite and converting all the SM, in VR runs at 36ms....so definitively something is not working as expected. I'm quite surprised that in 5.1 they managed to get Nanite and Lumen working, and even though there's a lot of room for improvement and optimization, I'm very happy that Epic decided to upgrade their tech to work in VR.

So glad I found this video!

Awesome video, thanks for covering so much. One suggestion would be to reconfigure your recording software so your mouse cursor can be seen in the recording. Seeing where the cursor is moving as you click around is really helpful in being able to follow along. I do have one question if you happen to know -- toward the end when you enabled the projectiles to emit light, do you notice a strobing/ghost effect? Hard to describe but basically the motion of the balls (or at least the ticks/frames in which they emit light) is fairly low compared with other motion. Imagine tossing a ball in a dark room with a strobe light going so that you only see the ball move through the air in a sort of stop-motion like appearance. Do you know of a way to increase the rate at which the ball emits light per frame or tick? Thanks again!

Hi! Excellent video but I do have one question regarding one lumen feature I couldn't get running in VR and that's proper GI. The room is still very dark and you're not getting the light bouncing into that room really. There's just the direct lighting. Could you show how to do this? I realize it might be computer intensive to get a good result with decent frame rates but for our use case that's not a problem and I'm sure there are many others who are also looking to use vr for product showcase rather than commercial games.

It would be so useful if you’d repeat a similar video to this but with your 4090 focussing on settings, quality and stability. I’m not sure how much practical insight I’m getting from jsfilms and your impressive samples pushing it to the limit in big open worlds.

Next question (I'm sorry, I am completely new to UE) - I was wondering, how do I illuminate the objects more in dark areas?

oh yea, forward shading, msaa, baked lighting is still by far the most performant. this guide is more like if you NEED to use Nanite/ Lumen, here's how to go about it.

For some reason the only way to manually change the resolution scale in the Engine Scalability Settings is to set the quality to epic and manually downgrading each and one of them to medium. This way the scale remains at 100%. If clicking on Medium, it sets it to 70%, and there's no way to change the scale resolution on its own.

Great Video I tried around by myself for a whole while before I found your video which worked wonders I am currently facing an issue in VR: The VR-Templates Hands and everything I pick up and interact with kind of... stutter. It is very weird, everything runs very smoothly, but my hands and objects I pick up seem to almost run at lower fps than everything else (ik that this is not actually what is happening but it is the best way to describe it). It is also only an Issue in the VR headset itself. In the View that opens on my desktop when running the project it everything runs smoothly. Pretty sure it is caused by Lumen Shadows. It even occurs after setting the Pixel-density to 0.1 so it is definitly not my GPU capping out I think? Does anyone else have this issue or can point me in the right direction on how to fix this?

Post process has always worked with mobile, you just need to select “mobile hdr” in project settings

hold on, when you tested in VR at around 27:50 you didn't wear the headset or used controllers. How did you manage to navigate in VR test without wearing the kit please?

hey there, is it possible to set up a VR project without starting in the VR template? if so, how?

@ibrews

Yes you can use any project. Just enable the OpenXR plugin and “start in VR” in project settings

​@@ibrews So can start a project in the architecture template in firstpersongamemode, and the only thing i need to do is download the OpenXR plugin? or do i also need to set the gamemode override to VRgamemode or something like that?

Changed some of those non raytrasing project settings suggested. Now all my UE5 project crash under startup. Spent 3 hours so far trying to fix this. Reinstalling 5.2 now i hope that works Got a slow computer here

​@@ibrews okej thanks for tip, i actually solved the issue, it changed the VR platform for some reason, had to reinstall My Valve Index and then UE5 works again odd but yea. My guess is that "HMD Fixed Foveation Level" is what fcked it up for me. but i dont knew.

Looks strange that the walls nevertheless stay pitch black.

You mean the reflections? Changing reflection mode can help

With your settings in the video my engine is not able to render translucent material as water. Is this possible? Why is that?

So what’s the status quo for now for having a performant(!) VR Scene? Avoid Lumen and Nanite (for now) and go oldschool and bake everything what’s possible, SSR?
