Hai!
Im wondering if I can set a nodes rotation to be free.
So that when the node spins, all parts attached to it doesnt have to spin, they hang like jointed to the
skeleton?
Because I find jointing quite difficult 
Not if you do it with a Node-tree. Child spatials always rotate with their parents. You could update its position each frame according to the "parent", removing the rotation factor. The problem is that the rotation of the parent also defines the location of the child if the child is not at the center of the parent, like your stretched out hand when you just rotate your body 
you could just make the node you want to rotate a child of a main node for example.
sceneNode
node---- playerNode ---- Box (or player or whatever)
|
|
|
other child nodes----more child nodes
|
|
|
and more child nodes
because what you probable have is;
sceneNode
playerNode---- Box
|
|
|
other child nodes----more child nodes
|
|
|
and more child nodes
Using the above example you could rotate playerNode independant of the rest of the tree. Basically just isolate the 'free node'.
yea but I wanted em to simulate joints, but it canot be done so nvm
