A sphere spawn shape centred on the birth position. The shape takes the offset (r, 0, 0) and turns it, the birth velocity and the birth acceleration by a random angle in 0..360 degrees about Y, then by a random angle in 0..360 degrees about Z.

• In surface mode (flags bit 0x1 clear, see VfxShapeVolume) r is radius.
• In interior mode (bit 0x1 set) r is uniform in 0..radius.

Both angles are uniform, so the samples cluster toward the two poles on the Z axis. In interior mode they also cluster toward the centre. A birth velocity along +X points away from the centre in both modes.

Radius of the sphere, in world units. In interior mode it bounds the distance from the centre.
