Duplicated instance blueprint: know if active or not

Hello world !
I have a big problem since yesterday,

I have a blueprint instance with “looking action” ,
When I look a mesh, I change of camera which is at the same place as the mesh.

I desactivate this mesh collision “OnBeginOverlap” ( a mesh around camera, it works), but i can not activate collision in all others instances of my duplicated bluprint … So when i have seen the point, i can not go there again after.

I have trying to add onEndOverlap but can not find the fonction…

Thanks for your help guys


Trying to do it, OnBeginOverlap works, but the collision before changing camera won’t works,
Maybe because i need a custom collision option ? (like by default), but how can i do that in blueprint ?
