Wolfenstein TC - Custom Maps?

[plynthus]

Is it possible to import your own maps from "gamemaps.wl6" to Wolfenstein 3D TC?

I couldn't find any info or instructions about it.
I tried the Maptowad that was available here: "http://www.afadoomer.com/wolf3d/downloads.html"
but I couldn't open it in the game.

You need to build the nodes manually. (necessary programs included with Doom Builder 2 or GZDoom Builder)

However, when in game, you'll see HOMs around you because the wall sidedefs seem to reference the Wolf3D textures. You need to retexture everything yourself or provide the necessary textures.
Also, all the sectors seem to be unclosed...

Maptowad is a program, not something you open in the game.
