Beta's looking pretty great so far! I honestly can't wait to see what you do with the skybox.
That being said, I'm noticing some weird pop-in issues with the rooves and buildings around the map. It's not too noticeable and won't interfere with gameplay, but I just figured I'd mention. Standing in places such as those shown in the screenshots below cause the buildings nearby to have their textures turn invisible. There's quite a few spots that do this, so I just figured it'd be worth mentioning!
As well as that, the handrails right next to the point are not clipped, and you can walk right through them, which I imagine isn't intentional. Other than that, map's looking great! Congrats on the artpass. Keep up the good work!
