Is it possible with blueprint entirely - if so: could someone point me in the right direction? ;D
When I say “Climbing a moving monster system?” - I generally mean what was done in games such as Shadow of the Colossus and Dragons Dogma!
Thanks,
Hello,
If i had to do it, i think i would try to set sockets on monster and use them as attach point for the climber.
I would go deeper, define physics material on the monster, and do ray queries to figureout of it’s hair or grabbable, or if it’s a hard surfaces with a grabable edge relative to the gravity direction. query the forces applied and a attach the character by the hands to the point and raggdoll the rest when forces become to great due to the monster moving.
To answer your question, yes it’s possible. It’s not going to be easy though, lots of people are trying to create climbing systems I guess since those white hooded dudes started jumping from towers lol.
I would suggest mastering adapting your player’s location first, after that try to make certain ‘grab points’ if you will on a wall and try to make a system that snaps your character to those points when you hold a certain key combination.
Work your way up like so. 
Good luck
