This won’t help with the headroom problem but if you hit your toggle UI key it hides the character avatar boxes. You still can’t see the very bottom of your feet but you can see a lot more of your shins. You also can’t spin your character in place with the UI hidden so for screenshots you need to position, toggle, screenie, toggle back on.
I wonder how difficult it would be to have the Asura display higher up on the screen? Maybe with the little “terrain” patch moved up as well, if that’s needed to keep the character from looking ungrounded/levitating?
