Nagus or anyone who can help ,could you explain how to do the switchable light with the 1.3 mod ,I looked at the demo maps but I just cant seem to figure out how you did it ,Thanks.

What don't you understand about the setup in the demo maps? (keeping in mind I've never seen them)

I dont understand how the lights are triggered on and of ,I think It has something to do with "light styles" ,but I'm uncertain how to do it.

IIRC Nagus told me that he did those by using func_static entites, or something like that to do it.

THe idea was to build 2 versions of the same room in the map. One of them would be lit up w/ lights, while it's duplicate would be dark and unlit. Then, you set it up so the 2 rooms swap positions really quickly on the touch of a button, so is appears that the lights have turned off.

I see ,you could do some interesting stuff with that.

I think I understand about light styles it must be a way of causing a light to strobe or flicker.

Yeah, lightstyles are done using a q3map2 hack, but your maps performance can really take a hit if your not careful.
