Do you happen to know why would HammUEr (source build or pre-built binary, tried with 4.19.2 and 4.22.3) not generate materials for Quake 1 and Doom 3 maps ? I was messing with it last night and while 2 folders (Materials and Textures) are created by HammUEr, Materials folder has a few empty subfolders and Textures folder is full with properly imported textures.
