Made some changes. The problem most in need of addressing was the opaque water backsides, which meant you couldn't see out of the payload water sphere. All water has been replaced with cheap water.
Other changes were to clipping, pickups, Z-fighting water, and small changes to stop red being able to hold indefinitely in places besides the actual cap areas. Finally, it was pointed out that it should be easier to get into the actual Payload water sphere. Originally I wanted it to be up high, with surrounding geometry letting you jump into it, but it proved too awkward in spots so I've lowered it in areas.
