I set the weapon’s SetFirstPersonPrimitiveType to “FirstPerson”, but the weapon still clips into the wall.
I attached the weapon to the arm skeletal mesh using a socket.
Besides just scaling the player camera and weapon models (making them smaller) to stay within player capsule - you can use a separate FOV for the arms and weapons in different ways, for example:
Which - I believe - changes the location of the material in world space and layers/renders it on top of everything else.
Hope this helps
