As I mentioned in our conversation most of the image/sound/speech assets are in the assets/lotr/ directory (in various sub-directories).

@Sinthoniel A resource pack is capable of replacing almost all image/sound/speech assets so long as they reside within the assets directory in the modfile (jar). As for modifying world generation that is more than possible by grabbing the chunks after LOTR has generated them, but before they are populated. Doing so would require the creation of a seperate mod/plugin though. Both of these types of modification are possible without changing the original modfile in any way. You don't understand me. Minecraft (or Forge, I'm not sure) has a place where it loads all the graphic resources - and replaces them by resourcepack graphics if available. But for some graphics the LOTR mod takes them by finding the mod file (a mod can get the position of its file from Forge) and loading the graphics directly from there. No resource pack can change that.

Believe me, I'm a modder and I've seen, and mostly understood, nearly everything from the source code of the LOTR mod.
