I'm trying to use different arms. I have used FPS Mesh to separate the arms from my character. From there I have set up a FPS character with the body that was separated from the arms. I run the scene and everything works as expected. I can move and see the feet of my character. At this point I go through the first person item creation video. After this the arms and item are visible in scene view as the image shows. However when I enter play mode the arms and item disapear in both the scene and the hierarchy. This first image is when not in play mode. The second is when in play mode.
