entity with updated plugins (1.4)
1. Open your map in entity
2. Go to [Vehi] objects\vehicles\warthog\warthog
3. Go to the camera marker name string and type in "camera_driver"
4. Go to Camera submerged Marker name and type in "driver"
(press the down arrow on both boxes and select the string you just typed in, or else it will
be saved as a null/plaintext. Then save)

Now we will make the default view to 1st person, (this is unnecessary if you are going to use yelo with this)
5. Go to seats reflexive 0 and uncheck driver seat, (it is actually the perspective toggle lol)
there you have it, proper 1st person view, you may fool around with camera stiffness and looking angles to improve it.
