How do I separately bake lightmaps for different objects in a scene?
<p>Suppose I have a scene with two discrete states: </p>

<p>DAY: the sun shines on a cube at the origin</p>

<p>NIGHT: the moon shines on a cylinder at the origin</p>

<p>All the aforementioned objects (sun, moon, cube, cylinder) are static; the day/night transition consists solely of selectively enabling and disabling them. Is it possible to bake lightmaps for the cube and cylinder separately, so they'd look as they would if day and night were two separate scenes? If so, how?</p>
