Rav I noticed that you had on the caulk_hull map, you had two layers of caulk.
One off a complete surrounding of the rooms
and another on the back faces of the brushes you used.
I'm thumbing through the manual, and from what I gather you need a shell(hull) for the structral to do vis blocking and the internal shell (room) for texturing the detail.
That sound about right?
Or is that just for compile times, if only the faces the player sees are textured and the rest are textured in caulk...?
