I did give the action mapper a go, but unfortunately zoom, sprint and targetting are under the player section, which I believe makes them the same across BA, Mechs e.t.c.
CapperDeluxe, where can I find actionmapper.xml, and the xml files for other action maps I've created? I can only find default_actionmaps.xml, and actionmapper.xml files in the documentation folders, and nothing in VirtualStore.
