How do I reference a held mesh to another controller?

[anonymous_user_e266909e]

I’m trying to add a mesh that one controller is holding (or intersecting) with the other controller.

(Eg) L Controller trigger is holding/intersecting a shape — R Controller shoulder button held down makes the shape that is being help by the left one.

I hope this question makes sense,

Thanks!
