In case of 2D skyboxes it is possible for this hook to always be called with this parameter set to
Draws a solid black sphere at where the player is looking at, but not when the skybox is being drawn.
You can see why this is needed if you disable the skybox check and look into the sky on gm_flatgrass (or any other map where the 3d skybox is below the map) and you will notice 2 spheres and not 1.
