| Also note that closed meshes with normals facing away from its center (i.e. a closed room) cannot cast shadows since the shadow will be omnidirectional and will fill the entire screen. This will most likely only apply to scene geometry and the ways to fix it are the following:\\ | Also note that closed meshes with normals facing away from its center (i.e. a closed room) cannot cast shadows since the shadow will be omnidirectional and will fill the entire screen.

Unlike static map meshes (see [[content.creation.document#creating.maps|chapter 3]]) you don’t have to add a “nocollide”-parameter to show that the model doesn’t have any collision, models never have any collision unless it has one or more colliders. | + | Colliders are used by the physics system to calculate collisions.

To get the positive direction place your thumb on your right hand in the direction of the axis. Now bend your fingers towards your palm, the direction in which you fingers are pointing is the direction of the positive angle. In mathematics this is called the right hand rule.
