Ok, here's the thing: I've been attempting to get GTKRadiant to edit Jedi Academy by using the new NPC def files and textures. When I go to point GTK in the right directory, it loads up and stops, saying that essential textures are missing.

Now, I've checked for myself, and these textures do exist. It's just that they're in png format rather than jpg or tga.

This is GTKRadiant 1.3.11 by the way, but I've heard there are newer unsupported betas floating around somewhere. (presumably with png support for textures.)

This is really my only stumbling block, seeing as how I can compile a map into JA and it will run just fine. (Sans any textures that weren't carried over from JO.)

Any advice?

Convert the textures to JPG.

That's nice, but I don't want to have to get BitTorrent or something like that in order to get it from there.

Got a problem with BT, huh, do ya, punk?

:p Had to do that ;) But really...what's wrong with BT? Small dload, helps you get files such as GTK...
