Does Q2World support the same style of skyboxes (such as the rolling clouds and nebulae in Q3A). That was always an impressive feature in Q3A maps and something I always hoped for in Q2 mapping.
Currently we just have the old Quake II skyboxes, but adding a cloud layer would not be that difficult. I've wanted to look into this for a little while, now. Maybe I'll take a stab at it this weekend.
