Thank you. I am just getting ready to do the "Animation in Blender" track when this posted and I knew I'd need it to learn.
You posted though for the Gun Turret blend file the Crane Arm blend file. Could you change it to the Gun Turret please? Thanks.
Thanks, Agro.
I will fix that real quick. However, all the files are also available in the source files zip. (on the first video page. https://cgcookie.com/lesson/fundamentals-of-rigging-intro-chat)
Look for the cloud download button.
