I can't find a workaround for this and it's really bugging me. Whenever I crouch I am looking through a black and blue error.

Thanks in advance for the help! :D

Is the player model itself an error?

No, it is just the legs of the playermodel.

(edit) And I do have to mention that this is on NutScript
