Custom Attachments

[SilentStriker]

I am attempting to create a mech based game; I am trying to make it so the base unit will be solely the torso of the mech. From that point I would like to be able to attach legs to the mech through a dummy ability (give the ability attach mech_legs to "foot+left" or right doesn’t matter). My problem is that I don’t know how wc3 determines where the points hand+left, foot+right, chest, ect. are on the model. I was thinking it might be through bone names, but I’m quite new to this. Thank you in advance for your help.
