Hello guy i am having a problem i made a first person project and started making a level but later realized i wanted true first person so i add the assets from the third person starter map and setup my true first person character. But the problem is that i never spawn as the character in the map i spawn wherever my editing view is and the character i spawn as is way to small and i cant edit it. I have check world settings and maps and modes to make sure it is on the right gamemode and pawn but still doesnât work please help! I dont know what to do. It spawns as the true first person character which is good just not as the one i want that is set in the map. I did try to place a Player start as well but it does the same thing just spawns me at start doesnt actually spawn as character i want. Video of problem below.
There are few things that could be happening here:
Check your Game Mode and make sure the correct character is being spawned (you probably have the wrong one here)
Another thing to check, on the Editor, click on the arrow next to âPlayâ and select âSpawn on default locationâ instead of current camera
Next, check if you have a Player Start
Let me know if this fixes the issue 
thanks for your comment the correct character is selected in the game mode and i tried to change to spawn on default location but it is grayed out i cant select it. Thanks@
Replying here because I ran into this issue, and while I believe Coquiâs is the most correct, there is another cause (completely unrelated) which will appear as a very similar problem: the in-viewport will begin to run, but the character will not spawn.
It can occur when the âPlayâ button has been set to âSimulate.â Fix: in the Play buttonâs right side dropdown, make sure the top option âSelected Viewportâ is selected. 
(I can attest to the frustration of trying to troubleshoot gamemodes, blueprints, and pawns, before discovering that pressing âsimulateâ in that one blueprint⌠yep that had done it.)
