Portals making things invisible

[MrMan]

Ive just run my map with areaportals on, there no leaks or errors such as 'portal does not touch two spaces' as i fixed them all, however, everything thats portalled off is turned invisible unless i go inside that room or whatever, in which case everything else turns invisible.

Is this because i am only running on fast VIS not full? Or is it a portal problem. I only ask instead of running full vis as full takes ages

Make sure your portal is set to 'open' in its properties.

What he said, portal are like door that can be open/close , always open, etc..

Yeah all the portals were set to open, the problems probably because im not running on full vis, i just came on here to check if it could be anything else
