VR Expansion Plugin

so what if i was creating a blueprint for each climbable object, and using collision messes inside it to highlight very specific spots on a mesh that were gripable. like only being able to grab the bars on a ladder. openings in a wall, or the top of a handrail.

also noob question. i was importing my gun models in and playing with it. and im on a bit of a run as for learning on my own as to how to handle weapons. but somehow im not able to figure out how to check the overlap from my hand and a button on the gun. how should i handle that
