Options Tab
Use Polygon Selection
If the texture tag is limited to one Selection only (see chapter 18, “Texture Mapping”, p. 869 in your
CINEMA 4D reference manual), selecting this option ensures that only this selection will be baked.
Evaluate Bump
When active, this option takes into consideration (for effects created by normals) changes made to
the orientation of normals caused by the relief channel.
Use Camera Vector
Lets you dene whether or not the current camera angle should inuence baking. This would, for
example, have an effect upon the “Fresnel” effect of transparent materials. Another example: This
option should be deactivated if you have a sphere onto which you want to bake a sky reecting onto
it. This will ensure that the object normals are calculated in the direction the sky is mirrored and not in
the direction of the camera angle (this would lead to unwanted results because the reection would
be calculated from the camera’s angle of view).
Color
Use this option to bake a particular object’s “Color” material channel. If several materials are applied
to the object, the various color channels will be merged according to their hierarchies and alpha
channels.
