I'm trying to open the original Quake map source files that John Romero released and re-render them with much more detailed lighting + radiosity and other general improvements made to BSP mapping in 30 years.
However, when opening the Quake map in Trenchbroom, textures don't show up. Even when I put all the Quake textures into the explicit texture directory (even made sure they are all upper case like in the map file) they still show up blank despite displaying the exact material required by name (picrel)
I thought texture replacer would work, but it doesn't detect not-found textures as applied, so I would have to click and swap every face manually, so fuck that

Any advice?
