I’m trying to open the door by the assigned angle on blue print but it keep opens the door by the open angle on the c++ which i assigned it as 90 , whne im trying to change the angle on the blueprint Z: Value to for example -20 , I step on the pressure plate it opens the door with a 90 degree help please !!
