So first off ild like to say well done to the devs for what you have done more so in arma since it isnt the easyest engine to mod.

Now as for my suggestion ild say its half/half purely because when i saw you had bi-pedal mechs first thought was maybe arma3 engine has finally supported this better, well not from the looks of it anyways the hellhounds the walking animation it looks as if the root bone of the rig is getting/has movement frames making the strange offset while walking were the hips should have the movement and from my understanding arma engine doesnt have much in the way of IK retargeting and if it does is prob locked to characters and the only mech ive ever seen in arma that moved well was some 4 legged mech in arma2 however it was a player character in saying this surely adding a script to just overtake the character would be quicker and allow for more dynamic and fluid movement but anyways thats just my thoughts.

And again well done for what you guys have done and the time you have invested in this mod i say this from one modder to another keep up the great work and if there is anything i can do to help feel free to add or contact me

Regard B.Cheers
