Creating a one-way clip in Q3

[Pardner]

Hello,
Not many Q3 mapping sites left, hope this reaches someone who can help! I am creating a team based map and I would like to create a spawn room of sorts which lets players out of the room but does not let them back in. I do not want to use a door as I just don't want people to be able to sneak back into the spawn room. I think I remember creating one-way walls mostly by accident but I can't seem to create them now.
I've tried creating a brush textured with all no-draw except one face which is covered in player-clip. I've tried multiple surfaces textured in player-clip. I either get a brush that is 100% clip or 100% no draw.

Any suggestions?

Thanks - Pardner

A "Simple Patch Mesh" out of player clip should do the trick.

The front side (textured one) will block players, but you can walk thru from the back side.

You can also teleport one way from the room

I guess you could also make the texture transparent, placing it in whatever non-clipping brushwork/model to represent your one-way route.

This would give you full control over the visual representation.
