I dunno what he did to fix it. lol.
He just told me he used an auto rigging tool, so I'm guessing it's something to do with the rig. It's possible it isn't completely set up when we start but I dunno. I'm still an amateur in animating :/
He fixed the compile.
It happened on my sword animations and he fixed them so the arms moved. I have a feeling there is an extra step that 'we' aren't doing to get the arms moving. Whether they aren't rigged properly, or we didn't set it up right.
Is this similar to what yours are doing: ?
That's the one I use.
I have the same problem though.. Certain times the hand the gun is linked to works fine, but the other one is frozen at the idle position.
I got redrogue to fix it for me, no idea what I did wrong :/
