I don´t know about Quake, but it´s a shame that something as ordinary as the example I showed above for the door and wall doesn´t have a simpler solution than manually tweaking the door´s material to fit the surroundings. I know Unreal isn´t aimed towards ArchViz, and I´m still fairly new at it, but not having an option to easily match a door to its surrounding static meshes is a little bit of a pain…
