Hey @Andreakyy
can you show the component list of your door and what you do inside your BP_FirstPersonCharacter to trigger the event EventToggleInterfaceFocus. You overlap the collision box, activate the Linetrace bool, do a linetrace and when hitting the door activate the Interaction bool and set the custom depth?
Check this (or you observe the execution flow of the blueprint or add a brakepoint) :
If this prints "Hello"or what you put inside then =>
Does it only work inside of the other collision box or does it work because the door is outside and it is a collision problem of the door and the door frame.
