Back after a month or so!
This update brings:
*Basic 3D skybox on the blu spawn/B point vista
*Merged the pre-C rooms into one, made the geometry *slightly* less awkward
*Made it so that red has a harder time pushing into the room that blu holds from - now the staircase on the left side of C (blu approach) is a dropdown, and is on slightly lower ground than the large ledge that blu has. Red's only entrance to this area is the large, fairly exposed main entrance to C now, and a proper blu sentry spot on the ledge should easily counter it.
*Misc changes to geometry around C + textured the tops of beams so it's clear you can't shoot through (thanks Bikkie)
*Clipped some small ledges
*Made moneyface platform taller so it looks less like you can jump onto it
*Fixed clipping in pre-C area to stop perching
*Added a room for defenders by C, replacing the awkward and useless barrel mess that was there before
*Made C's room a little thinner to aid red defence
*Stopped red team from using the A spectator cam after the point is capped
*Made blu's first spawn's gates cooler
*Perhaps some miscellaneous changes I'm forgetting.
Thank you to everyone who's tested A30a, as well as all the other versions!
