Hi guys can someone please help me i need help on switching from first person to third person without changing map when i press the play button it shows up a first person but i want my character in thirdperson

have you tried setting your default pawn to be a third person one? how about placing the third person character in the level and in the details panel set auto posses to player 0.

theres several ways to accomplish the using a third person in your level. also did you want it only in this level or for every level, theres methods for both.

you can try in this way. add one more camera and attach it to the head socket. leave the default camera as it is and change the camera views when ever required.
