I encountered a bizarre problem with the First Person Character model. Uh… it’s hard to describe, I’ll just show you the two screenshots (I tried to remove my new game over blueprint because it appeared after i finished it - no difference):
It looks like you have missing weight information on one of your model vertices.
If this model was brought in, I would double check in your 3d program the skinning information and then re-import the mesh. Double check in the import log for any errors about missing influences…ect…
