So I was working on a scenario using the 3d editor (build0039) and was looking for some terrain items only to find they weren't in the sidebar. So I tried using the standard old editor but they weren't there either.
To be specific I was looking for the barrels on their side from sheet g720. I can see they are in the proper terrain graphics directory though. Going through those files I noticed there were a number of other terrains missing from the editor.
Can anyone clue me in to what I'm missing here?
