Just wait a bit longer. I was thinking the same, and started to investigate thru DevTools, finding 403 for https://temple.tiwsamples.com/media/3e0ec554-aaab-403c-9b1e-..., but it seems that before app loads it should play some kind of video (which cant find) and after it complets this it loads the app (even on very old laptop)
Sometimes porting this stuff is a fun intellectual exercise, or sometimes it’s a version 1 precursor, or sometimes it allows for a much simpler setup to run super smoothly (e.g. a visualisation tool)
I find things like this fascinating, inspiring and interesting, all great things have small beginnings.
What a pessimistic way of trying a demo haha, the fact that a UE5 game can be ran in a browser is already impressive, performance is definitely something to work on, though.
I'm curious what the smallest build of a minimalist UE5 WASM game word be. A cursory googling indicates you could probably get a desktop x86 UE5 example project to an 80MB build. It might be hard to take advantage of UE5's advanced feature set if you need to cut back on assets for web. Not to mention the bandwidth costs for recurring users.
