The Superku character from 2006 was even a popstar.
Haha I had already forgotten about this clip, thanks.
Update:
I've written a basic simulation for cape physics, almost everything is calculated inside the vertex shader (2.0). I only use ent_animate to bring the cape into a basic starting situation, pan-rotations of the player/ Superku are taken into account (compare second screenshot).
The most difficult part was to implement a smooth transition between a cape that simply hangs down, e.g. when Superku holds on to a ledge, and a cape that touches the ground (see the end of the video).
