Surface Color
The effect of the bump channel can be seen in the surface color (right, the baked texture).
The surface color contains the effects of numerous material channels, including “Illumination”, GI
and cast shadows (not including “Reection”, “Transparency”, “Fog” or “Glow”). The most important
material channels that make up the object surface will be made a part of the texture.
If a texture baked in this manner is placed into the “Luminance” material channel, lighting the object
when rendering may not be necessary, as long as the light source(s) and object don’t move. This will
result in much shorter render times.
NOTE:
When baking GI, light that falls on the reverse side of a polygon will be ignored
by the Baker!
Light
“Illumination” only bakes the Spot light source’s lighting; top right, the “Shadows” option was activated.
“Illumination” includes the effects of light sources and, when active, those from GI. If the “Shadows”
option is also activated, any cast shadow that may be present will also be taken into consideration
(see insert above).
