Next, set the light's rotation to
H=0
,
P=0
,
B=0
. This will give us flat, even
lighting on our explosion, letting us
manually “sculpt” its shading. (The
default light in a scene is a
distant light
.
Its position doesn't matter, only its
rotation
; all the rays are parallel to each
other, like a light a very long distance
away. Having it oriented the same
direction as the camera means that we
will have flat lighting on our explosion.)
