Help with Using Rigged FPS Arm Model

Hey everyone! I'm a total newbie with Unity, but I'm trying to create an FPS arm (got a model from Blender) that's rigged, but I'm not sure how to use it. I'm trying to just get an animation out of it for now. There is definitely parent/child relations (fingers are children of palms are children of forearm... etc.) but when I try to move a part, it will warp or stretch the other parts instead of moving like joints. I know this might not be very detailed but if anyone even knows how to just get started that would be awesome! Thanks guys!

 

Are you trying to animate this in Unity?
If no - consider reposting this in the External Tools section for help - in blender.
Or - maybe posting in a blender forum would get some assistance.

If yes - don't do that. Animate in blender then export to Unity. And check the learn section for more info on what to do after that.

 

I'm using: http://www.blendswap.com/blends/view/69488
And I'm trying to get a simple user input = make a fist animation, if that makes any sense?

 

So you created the animation in blender and exported it into Unity.
Then confirmed the animation works in the inspector preview, coded it up to create a a fist when the user clicks a button?

 

Check out the skinning in weight paint mode. Maybe the vertecies are not connected to the bones as they should be.
