Can i apply perminant gravity?

Hi. Is it possible to apply perminant gravity to a level?
I want to have a level were you float around with low gravity, is this possible to do without starting the server with the setting?

Thanks.

What are you running it in?

Zdaemon

I don't know how exactly but you can set the gravity to an individual level even if the rest are normal;
i.e. tlsdm2k3.wad (or was it tlsdm2k4.wad?) with the seperate moon level and both work with Zdaemon

You can set it via an "open" ACS script, or you can put it on a linedef and have it activate by someone walking over it.
