ok...
my guess is you will not get most of that (i'm no expert really, so...), since its mainly DX content. I could suggest you just move on from some of that deco you want to place in the map. Is it
really worth it to include it?
The 1rst thrash can you can do it easily with the UED 2. The 2nd in FIRST screenie, maybe. Do the same for the 3rd pic can (how hard can it be, to make something
similar ?), and simply forget about the 2nd image things.
Unless that some UT-engine code maniac can help you importing and converting (if necessary) from Dx. I know that is beyond me, so i can't really help
You could always use some UT default DECO content, like some thrash cans, like in Morpheus (i think some are in that map, or Stalwart... i´ve moved from UT most of the maps that came with the game, leaving but a few and custom-made ones)...
