To limit the amount of geometry rendered in the shadow map, and also to reduce artifacts (shadow acne), only faces not facing the sun are casting shadows. The test is made using the normal orientation. That means that double-sided polygons, or mesh that are not closed, will be transparent to light at certain sun angles. To avoid that, modelers can either : | |||
* ensure that the object is always in the shadow of another objects, | |||
* close their mesh, or, | |||
* double polygons with the normal set to the opposite. | |||
