Hey man. I just went that route by casting from the weapon BP and getting a reference from this same BP but coming from my character and even though I can get to the same skeletal mesh that way the problem persist. Kind of redundant doing it like that but it didn’t work anyway. I might have to find another way to do this first/third person show/hide stuff. Or maybe I should find someone that knows how to use that node as I even tried to use it in the Character BP and it didn’t work either. Always the same error.
