Need help Ripping Total War: Warhammer Weapons?

I’m trying to figure out how to get the Ork / Beastmen weapons from the Total war game. I’ve seen some people recomend Ninja Ripper or File manager but i can’t seem to get either to work well enough.

I mean with file manager i think i managed to find the weapons in variantmesh but they’re all stuck on a "Variantmesh’ filetype and i am not sure how to convert that to .Dae/ anything that works in blender.

Could i please get some help with this?
