Citadel is probably even much more bigger than in the video, because at the end of half life 2 you are on top of it and its so much bigger. and yes its also undergound to the sides, there are striders transported in very long halls, So in reality it is waaaay more bigger than guy in the video said it is, its not big or huge, that thing is Super massive 🥶

[@elielc.8459]

That's awesome man. Never thought i'd see it full scale in an actual map and not the skybox. Makes me daydream about a Half-Life 2 remake where city 17 is, you know, an actual city, and not string of interconnected maps, with the game still being linear, but turning into a seamless experience without loading screens (not impossible since you just managed to make infinite map sizes), and when you get to the citadel you'd get to see the whole journey that you made instead of a jpeg of some city lights. Anyway, good work. Love the wizardry that you make in the source engine.

[@kabanod1m]

you know, if loadings are that long in normal half-life 2, imagine what it could have been if they were all connected into one map and you had to load THAT… well it's only one time, each time you start up the game, I don't think you need to reload the whole map to load a quicksave since they could just make it adjust entities' properties and not reload the entire map

[@elielc.8459]

​@@kabanod1m True! And with some good optimization work and clever map rendering (as in, the whole map would exist, but only the part you're on would be rendered) they could probably make it happen. Plenty of open-world games manage to pull it off!

[@Wheagg]

The big issue is that source has very tight limits on things that are pretty difficult to spoof. This does that using some serverside tomfuckery, which would not work for this since it would not even compile. Now I do think seamless loading is more possible... Just still incredibly difficult :)

[@elielc.8459]

@@Wheagg Right, that makes sense. It's cool to hear that seamless loading might be possible though, and I don't doubt it is. I'm not sure it's related, but I was surprised at how much well optimized Source 2 is in Half-Life Alyx, especially considering how beautiful it is. If it was a flatscreen game, it would probably run 60 fps, high settings in even the most mid tier of PCs. Maayybe it would make the game load faster? Either way, some engine code rewrites here and there could make it happen, but again, i'm just daydreaming lol.

[@Wheagg]

@@elielc.8459 There are a few things to consider for seamless loading. Firstly, is the time taken loading greater than the time between completing loading and finding the stuff that got loaded? If so, it's possible you'll see stuff before it's properly loaded. So we'd have to trigger loading earlier. Plus some people might be on slower HDDs and will need even more time. But to answer the VR question, probably, since iirc source drops the FPS to minimum while loading, something that VR can't do, which would consume valuable CPU/GPU time.

Modify it and try to line it up, copy its size, then Port it back to the original test map to see the real size

There are barely any dedicated physics simulators that can run something like that in real time if at all, let alone trying to achieve that in a game with a 10 year old physics engine not built for that.
