Hi,
one more question, does anyone know how i can give serverel gem objects own axels? now there is just one axelsystem on wich all objects are orient.
so it is for example impossible to let serverel objects rotate arround themself.

I was looking for similar thing and found this very useful. Give it a try..

[separator] is the key object, you can use it to build a tree of transformations instead of just a linear chain.
