This is the sixth in a series of Tomb Raider Level Editor tutorials. This tutorial details two commonly used methods of opening doors. This first shows how to open a door with multiple puzzle items. The second method shown is the use of multiple switch combinations to open multiple doors, similar to the setup used in Palace Midas in Tomb Raider 1. I am using TRNG MK4, but this setup is also the same as that used in the original TRLE.
