Character weapon animation questions?

You still add the weapon to one socket. The other hand is just positioned as if grabbing it.

If you have a weapon bone, you can animate that. If you wanted to be able to affect the rotation for example in animation, without affecting the hand.

You can add lots of things into animation Notifies, such as effects or sounds. You can combine that with Curves or MetaCurves that tell a weapon to appear.

So maybe you attach a weapon, an equip animation plays w/ a curve hiding it (scales it to 0), then an effect notify plays, followed by the curve revealing it.
