Single Status Update
I've spent some time exploring the EE-UDMF mapping format. It offers some more options for polyobject portals in particular that EE-DOOM format just does not provide. While seeing this stuff in small test setups makes you all giddy, it mostly is still too iffy to use in actual maps. Too many random visual / gameplay glitches, especially near other portals. Still, this stuff looks promising especially for a WIP... I wonder where the EE devs will be able to take this.
Part of the experimentation included the manual conversion of a smaller level to EE-UDMF format. Whelp. I sure do not look forward to the absolutely enormous task of doing the same for the other, much larger levels. Will probably have to write my own custom tool in order to keep myself sane during that process.
Not that I'm switching right now. There's no reason, yet.
