When you try to equip the weapon, does it stick to the groud and flip your character in an awkward position?
This usually means that the gun is not welded, or parts of it are anchored. Since our characters are unanchored, we can't move with anchored objects. Try taking an weld script (which you can find in all free model guns,) and put it inside of your own gun.
This will probably solve your problem if this is it, but the direction that your character holds the gun has to do with GripPosition, which I can show if this has fixed it. |
