That's what I was talking about, yes. Effect 5 makes midtextures repeat infinitely all the way up, but for some reason they render even when you're not looking at them which causes extremely strange issues when this goes way too high.I was talking about the bizarre horizontal lines (slime trails?) that kept popping up in the waterfall area, among other places,
as well as that one pillar outright disappearing as players ran behind it.
The camera no-clips of course! You can now see through stuff rather than it getting stuck when a wall intercepts the camera. This can be used to mapper advantages.
