how to remove weapon swing animation

[mayainverse]

i have been trying to edit my rogue to have instead of dual wielding 2 weps to using just a single 2h wep. was able to change my main hand to a 2h visual and its sheath position without trouble as well as its swing animation to its 2handed counterpart. and also could remove the visual model of my offhand but i am having an issue because the offhand still has an animation and messes things about. I tried to change the animation information of the specific weapon I am using in the offhand to just some random number like I did with the display id(that worked) but the game crashes with the animation one. so I am kind of lost here. even tried put in the value for shield did not do a thing
