I read about the music, and the word "convert" made me a little uneasy. I just removed the .mp4 from the filename and wrote .ogg, and it worked and played normally.
What the heck is .mp4? All sound effects are pure .wav (sound playback depends on the codec used), and music is .ogg :smile38:
In principle, the game engine can read other containers, but if these mods are to be used by other users on their computers, it is better to stick to common standards! :smile29:
