what do you mean with appended files?

the "substitute" option did the trick for me. i am not sure how to solve the animation thing in a better way. i think if you have a level filled with different animated character models then always exporting all models and all animations could take a while. it would have to be cached somehow. the animations only exported again if something changed...

i know that the exporter isn't really finished. after it did what i needed i lacked the motivation to polish it. polishing a program often is very boring and uninteresting work. smile ...and for myself it's no problem to add new features on the fly in case i need anything.
