sky light for a non-quake game

[verypleasentusername]

Hi, im making a game using trenchbroom and EricW Tools for mapping. Currently im making a map where i need sun light to illuminate a lot of things in the area. The problem is, whatever i do, compile tools do not recognize sky texture as a light source. I have tried multiple worldspawn and compile flags, but nothing works. I tried other maps from other people including official quake maps, the only difference being that skybrush faces in those maps have no light info on them. But none of them illuminate anything else.

map and the flags:

-q2bsp (for colored lighting, idk if important)
-bounce 2
-minlight 0.05

other flags are in the worldspawn

I wouldn't use the -q2bsp switch unless the map is also using the Quake II format. The Quake II format adds content flags and surface flags, one of which is for sky. Quake (1) maps rely on sky being identified by a texture name starting with "sky" which you appear to have from your file.

how do i make the map use q2 format? and how do i set surface flags with it?

1. If you care deeply about your map back it up. Then edit the original's // Format: Valve line to // Format: Quake2 (Valve) to get TrenchBroom to recognize the map as a Quake 2 format map.

2. You don't need q2 for colored light support, as long as you're willing to read light colors from an external '.lit' file

i changed the map type to quake 2, as well as created content flags for sky( im not sure i created right ones). But i can't see how to set them anywhere in trenchbroom. I tried reading manual "working with materials" section but its hard to understand. Sorry, im kinda new to this stuff.

In q2, sky is a surface flag, not a contents flag. Try the sky checkbox here:

Surface and Content menu doesn't show up. I double checked -- map is in Quake2 (Valve) format. Maybe its an .fgd issue. I tried doing sky the quake 1 method: i just named the texture sky and fair enough, compiler didn't calculate any light for that surface, but thats where good news end -- no sunlight showed up either.
