@ello: oh no, did I say that? For sure you have to change some things... if your model has not a normal human structure you must change some bones or some parts in the script! I will make an understandable tutorial for fitting the script to your models. And there will be also a tutorial that tells you how to change some little parts of your model to work better with the script.
For example: The finger movement looks better if your model has two subdivisions between the single finger parts. and than I show you how to make it with med or max...but I think almost every human model will work with the script, because it is very simple and depends on the bone-structure which you just copy to your model(or copy the model to the bones, don't give a damn about it)

Well, I make this tool to help the community, but I also make it for my games and I want to use it for every model I use...so maybe if it doesn't work with animal-models I will write a new script for me, and maybe you can also use it.

Sorry for the bad english, I am messed-up for today
good night, good fight!
