How should I convert a Doom format wad to a UDMF wad?

[_sink]

Hi, what's the current best way to convert a Doom format wad into a UDMF wad? Is there a particular tool or method I should use besides manually doing it by redrawing the level?

I ended up doing it the way a couple of forum posts elsewhere had mentioned: saving the map to a prefab and then importing it to a UDMF format wad. I yanked out all the lines and had to fix all the things i'd placed as they were missing classes (i dont know what those are). I just gotta redo all these linedefs now lmao.

The easiest way would be to convert the Doom_format map to DiHF (Doom in Hexen format)

with zwadconv.exe.

 

Then ...

• open the converted pwad with UDB
• press F2
• select UDMF 
• press OK

 

This will apply in 99% of the cases.

thank you kappes! this worked just fine and preserved most of the lines! i gotta figure out how to add the 3d mixtexture flag back to all my railings though lol, as this is an eternity map.

Assuming you're using some form of DB2 the easiest way is probably to use Find and Replace Mode (F3) to search for the texture(s) you used and edit the lines from there.

I love to do this manually because there are always improvements you can bring to your map while your at it. It also makes you learn the map's mechanics much better too...
