Hello all. I've used Vavoom to play Doom II wad. Now I'm making some experiments to create a new Doom II level. I know there are many level editors around, I've used Doom Builder. But now the question is: how can I edit a level with the enhanced featured supported by Vavoom? Like Room on Room, for example? Thanks!

You need to download the editing package from the downloads section on the main site, it contains the configuration files needed by Doom Builder, just place them on the same folder you have installed Doom Builder. If you need help on the way 3d floors work, you might read the Wiki documentation on the site, if you still have problems, post a thread on this forums <!-- s;) --><img src="{SMILIES_PATH}/icon_wink.gif" alt=";)" title="Wink" /><!-- s;) -->.

There are Vavoom configurations for Doom Builder 1, not DB2, as far as I know.
