I don't have too good a clue what to do in what order for beta mapping/testing, so all im doing is the best I can! I've looked through most of the detailing guides on tf2maps, but none of them seem to start from step 1 of detailing and optimization. Any and all advice will help!
I've made some slight balance changes to last and first, but I completely rebuilt the lighting, skybox, displacements, and spawns! Everything should work much better, and have less issues during testing, to allow for more gameplay-focused tweaks going forward!
