How do i use UDMF Convert ?

I'm having a problem using UDMF Convert, Basically i want to Convert a Map in Doom format to UDMF, i Downloaded UDMF Convert and ran it, My Map wadfile name is FantaSea.wad, How do i convert it to UDMF using this tool (Every part of it so i can edit it and run it in UDMF Format) ?

Instead of UDMFconvert use the following:

1. Convert the Doom format map to Doom in Hexen format with zdwadconv.exe. You can find it in utils050999.zip
It is easy to use, see the text file.

2. Open the converted map in GZDoom Builder. Use Map Options (F2) and select Doom in UDMF.

This way you can preserve most line specials. I mention most because not all specials are translatable.

I've always just used convUDMF, personally.

Oh, Hexen format offers everything i wanted from UDMF format, okay thanks .

UDMF format features everything Hexen format does, plus more. Assuming that you're mapping for ZDoom, it's best to map in UDMF and not Hexen format. Just saying.

Yeah , But i misselected the format and instead of selecting UDMF i selected the default format, built half of what i was planning and when it was time for 3D Floors and walkable mid-textures i noticed the format was Doom :S .

Srs tho all I gotta do is open it and browse for the map, even does Doom in Zdoom -> UDMF.
