i decided to add full tunnels for the trains instead of just a black silouette. i think they add good background detail but also they look better than just a flat black background.
here's what they look like with the train next to the player.
also since they're background elements that the player will never reach, i didn't bother cleaning up the verticies since that would be painful with how i built it. i defeinitely need ot read/watcha tunntorial on trenchbroom because now that i've played with it for some time, i'd like to know best practices goig forward.
but yeah happy the outer tunnels are done. i gotta work on the higher platform now which shouldn't take much work but i need to create a background exit and that might so idk.
