Okay, I got it right this time, it's awesome, could use a bit of refining, but alas I've worked all day on it. I don't think I'll up another example after this. This ledge hanging experiment is part of a bigger project. I always had trouble with ledges, but I was able to do this in a day's time thanks to C2.
In my final upload, I have an area where you can walk or run around and grab ledges. They're a bit tricky at times, but it's all doable.
Let me know what you think!
Hold X to run
Hold SHIFT to grab onto a ledge (only when falling)
Hit "Up" while grabbing a ledge to climb it.
