just wondering for example if you have a lightsource,which casts a shadow from an object, say a sphere.
If there is another object within the boundary of the spheres cast shadow, would that object cast a shadow also. or will the shadow be the same tone as the spheres shadow and therefore disappear.
ideally the second shadow would be darker and there for be visible
This is causing me problems when rendering lightmaps, because the secondary shadow is not visible.
