A very useful tutorial, although I have found problems when using Unreal Engine 5.1:
First is that, after adding the shotgun, the old shadows of the cannon are not erased well, generating multiple traces that take a second or two to correct if we are moving. I’ve seen that in the tutorial videos it also happens.
Second: I also found the same error reported by @Sarien Link to the solution.
If the character walks crouched, after two seconds his legs are immobilized and the character starts sliding.
Third: when crouching, we always keep our hands as if we were carrying the weapon, even if it is behind our back; I understand that we lack the animation to go crouching and not carrying the weapon.
Any ideas, @MathewW_EG?
