Casts spherical or capsular geometrical shadows. [BlobShadow] provides an alternative to traditional shadow maps, by casting simple geometrical soft shadows. Provided the number of runtime shadows is kept low, this can provide better performance than shadow maps. It is a good option when combined with lightmaps. [BlobShadow] requires a [Light] set to cast blob shadows, and should usually be used in conjunction with a [BlobFocus], to determine where shadows should be prioritized. Only radius index 0 is used with spheres. Radius index 0 and 1 are used with capsules. Offset is used to determine the shape of capsules, allowing elongation in any direction. Radius of offset side of a capsule. [b]Note:[/b] Unused for spheres. Radius of the sphere (or origin side of a capsule). Allows choosing caster type, sphere or capsule.
