Hi, if I import my blender character whit bones to unity can I use the bones to make animation in unity???
Yes, there is an “Animation Window” that you can learn about here: http://unity3d.com/support/documentation/Components/animeditor-UsingAnimationEditor.html
That being said, all you have to do is move the bones that correspond, with the part you want to move, make sure to name the bones though, or else you are going to have a VERY difficult time figuring out what bone moves what.
Hopefully that answered your question, if not just reply to this and I’ll answer it more specific to what you’re asking.
