Help - Removing a part of armor

[davidos1254]

Hello

I wanna ask for help on how to remove part of armor(from mod) ,in my case shorten the pants to have more skin revealed.

Now.. Ive tried doing this on my own by importing it to blender and removing few verticles but got invisible legs in game and incorrect arm texture, feels like im stuck.

Thanks in advance
