The first way is to use a straight down light_environment
The second way is to use and angled light_environment but you,ll have to have a wall for every type of angle (4 for every kind). Regardless of the method you choose the roof and the ground should be two differend brushes because the lightmaps baked in should be different.

add a version of the map without props because they lag

make a map with whole room brushes

excellent map, just make it spawn less props as it lags the hell out of my beefy rig after 15 seconds of door opening and since using it with ai is impossible as the ai refuses to leave the room you spawn them in. add ai node generation as well

Theres also a huge bug where if you open a door from the outside into a room you are in, you wont be able to leave the next room without noclipping out of it

use nodraw textures for invisible parts of the map

disable allowing physics gun for every func_brush

make the walls thicker so props dont go trough

if you mananged to add lightmaps, then make the spawn the same room and add some lights into it. the randomly generated rooms won't have lights if you want to make it creepy or add some lights into the rooms if you managed to do it

you can use nav_generate_incremental after walking into a new room to generate a nav mesh, big brain time

some rooms seem to work, others dont...i dont know the cause...it might be how the rooms are generated, anyway here is how i do it,
step 1: nav_mark_walkable (if the room even has "floor")
step 2: nav_generate_incremental (if the marker for the navmesh even worked on the room you are in)
step 3: nav_edit 1 and see if it worked, if it did not, yeah thats what my issue is, some rooms dont work like i said

Gym, bedrooms,upside down rooms rooms with no gravity park rooms

That's not how i intend to get a navigation mesh, I'm generating it procedurally, and not permenantly

I am in garry's mod and I opened keep in mind im at spawn and I go and a room to a staircase is there And I open the door to a dead end.
