Re: sounds.
I think I forgot to add information about sounds in readme. I've just extended it (will go into the next UModel build). Here's what I added:
Audio assets can't be previewed in UModel, it doesn't have any sound library built-in. However
you can export sounds. By default, sound loading is disabled in options, so if you'll try to
export any audio object you'll get nothing. To enable audio loading, you should either pass
option "-sounds", or check "sounds" option in UModel startup options window. Please note that
despite you may think that package contains audio, there are many objects in UE3 and UE4 which
are related to sound rendering, but they do not contain sounds themselves. For UE3, sound
objects are SoundNodeWave, and SoundWave in UE4. In older versions of UE they have name Sound.
Please see if this explanation is good enough, if not - I can extend this text.
