***Fixed***
I made a new character with the same models over again in the Character Manager, i had checked everything in the demo scene and had my character setup exactly the same way, same layers and components everything, even checked Atlas and Rhea behavior as they walked and it matched my scene perfectly yet my footstep audio still wouldn't work(fixed interval). So finally decided to just remake the character(really didn't want to), the only thing i did differently was i place the 2nd model in the scene before putting it in the manager this time, whereas before i was dragging it from the project folder into the manager,. Not sure if it was this or that i had messed up the structure of the character models somewhere but at any rate remaking the character from scratch fixed the issue.
:Edit
Also what i did differently was the first time i made a character with another model I didn't assign the "active model" slot as I was unsure whether this was something that just was used for debug and showed up in runtime only or whether I needed to fill the slot, then of course i got both characters meshes combined at runtime, so i deactivated one and away I went, ultimately somewhere in there I jacked something up, remade the character from scratch drug them into the scene first then into the manager and assigned the available model slot and footsteps now work.
