Fan of the work too… But I want to go further and suggest some things.
A ledge climbing kit on its own, even with parkour, only gets you so far.
Whereas there’s a gaping need for character / anim specialization etc.
Think about combining what you have here with a custom character creator etc.
It’d be huge! Why?.. Buying a character creator without parkour anims is a pain.
Same goes for buying a climbing / parkour system without a character & anims…
Possibly right next after Casting, the most common question asked on here, is about:
Mixamo vs Epic Skel / Pose differences vs 3D app rigging / blending / anims / timing.
This area is filled with more nightmares than everything except physics rewind maybe!
Talk to FTC about his kit. Someone could make an offer and take that project over???
Check out also what’s readily available for free: CoquiGames offers a kit but no anims…
Lastly, think about extending the range of Parkour based moves, look to action movies…
