Okay the brutes left hand marker name is left hand and I tried making him hold my custom hammer I've been working on by attaching a marker and ik point with the name left hand but it didn't work.... but I got the masterchief to hold my custom hammer in 3rd person to work right I just needed help figuring this out???

I have a custom 3rd person animation for him but it doesnt look right unless he uses both hands???
