Hello There!
Does anyone know of and or have any resources/ tutorials on how to make a dynamic free-form climbing system similar to that of the one from Zelda BOTW. Something that isn’t just climbing up straight vertical walls or being stuck to pre-made ledges like Assassin’s Creed. I’m trying to make an open world, exploration focused game and having a fluid system like the one from BOTW would be very handy.
If anyone knows of anything online, even if its paid, please let me know!
Thanks in advance 
I would start with defining how the climbing works.
is it on terrain or on custom meshes?
this affects how you will find some vertex locations to use as hook points.
With the hook points defined, you would have to setup your animation with IK to reach those spots.
this part will be involved as you need to math your way into solutions for reach, crossing of arms, and moving your root bone so that it follows or drives what is happening.
This is not particularly hard to do, but it is extensive the more actions and directions you account for…
With the added difficulty of being forced to use the IK system to match the movement to the hook points.
