ok I have about 750 hrs on Portal2 Authering Tools Beta, most of it just learning and experimenting. I have made and published about 5 maps from it. This time I am using linked_portal_doors and a sky box everything was fine until I made my sky box and a room for it. now the skybox, not the playable room, the skybox itself is showing up in rooms and places in the map and even interfering with normal game play like puting a wall in front of a hidden laser or placing the laser cube off the map and in the sky box (by aperince) I can see this when I use no clip to navigate. if I hide the skycamera then the map functions fine except for the skybox room of course. I have been trying tio fix this issue for three days with no fix in sight. can anyone help me with this issue.
