Small artifact that causes the black colour of the shield (located Under neath probably 1 shield's distance to the bottom left from the back)

Jup, thanks for reporting that in.
Will change that soon.

Removed black square under the shield. (In another DEV addon)
But it doesn't change that the shield goes dark sometimes.
It because hitbox goes tiny bit under floor.
Thats also reason why shield can be deployed.

Also changed FOV | POV of shield.
But its either you can't see it in first person or it flashes in first person.

Go into 3rd person view Fentis.
I do not recommend going into 1st person.
