Yeah there is even more to it than that, the player does not normally know the contours of that rock because the collision physics don't follow the visual contours to that extent, its much more of just a roughly shaped block underneath. And this sums up Star Citizen, for better or worse....
Anyother game he would be standing normally with his left foot on the side of the steep hanging in mid air or his right foot clipping into the rock, its the sort of thing where Chris would look at that and say "i don't like it, do something about it" and so they invented a system where the CPU will tessellate the geometry directly under the player so it can calculate collision and then program the players animation in so many ways and with such granularity and physics to react accordingly, the result is that subtle detail you see in that clip, depending on your perspective its what makes this game and project so impressive, or over the top waste of time.... i think the former.
Just like the image i posted a few days ago, i'm no expert but i do know enough about Ridged Body Physics in game development to know what they did here in getting the physics to behave in the way they do on this ship is incredible, and it looks awesome.

Anyway, the video..... it may not be high res, still processing, should be 1440P.
