Okay, here’s some more data, if it helps, since I’m in an pitfall I can’t get out from.
Camera Parameter Changer BP
The variable Camera Owner Target has my Player Blueprint (BP_Player_001). I couldn’t find the other way for targets to the components.
Initial Functions Trigger inside my Player Blueprint
I tried creating the Reference Variable, so I could have the Cast To’s Object pin connected with it, using the variable of Player Blueprint, but I always end up with the Cast Failed.
I also tried to place the Camera Parameter Changer BP in the world/level, but ended up with the same: Cast Failed.
