You can use color per vertex sets to switch between, merge, blend, or globally modify the colors stored on your polygonal meshes’ vertices.
For example, you can pre-light your scene by baking your daytime lighting to one color set and then your night time lighting to another color set for each polygonal mesh in your scene. For more information on prelighting, see Prelighting polygons.
You can also touch up your baked lighting results by painting vertex colors directly into your color sets. The Paint Vertex Color Tool lets you remove, replace (darken or lighten), or smooth the lighting baked on your vertices. See Assign colors to polygon vertices by painting.
In addition to storing baked lighting data, you can use color sets to do the following:
You can modify existing baked CPV color sets globally with the Modify feature using either an HSV attribute modifier or an RGBA color channel attribute modifier. The Modify feature creates a polyColorMod node downstream from the CPV color set.
The Modify feature is useful when you need to globally modify an existing color set and don’t want to bake the color and lighting for the object again. The Modify feature is also useful when you want to modify existing color sets to match particular gamma requirements of some computer and interactive games platforms. For more information, see To globally modify an existing color set.
To create a color set
The Create Empty Color Set Options window opens.
A new color set is created.
To rename an existing color set
Select Mesh Display > Rename Current Set.
Click the Rename button or double-click on the color set.
The Rename Color Set window appears.
The selected color set now has the new name you specified.
To delete a color set
Select Mesh Display > Delete Current Set.
The selected color set is deleted .
To merge color sets
You can only merge or collapse one color set onto another at a time. Also, merges occur from top to bottom.
The two color sets are merged using the Over blend style option; a blendColorSets node is created for the new color set, which replaces the original sets. The new color set is given the same name as the first color set that was selected.
To blend between color sets
You can only blend two color sets at a time. Also, blends occur from top to bottom.
See Blend.
The two color sets you selected are blended from top-most to bottom-most selection. This blend uses the specified Blend Style. A blendColorSets node is created for the new color set that is created. By default, the blended color set is named blendedColorSet in the Color Set Editor window.
To globally modify an existing color set
A polyColorMod node is created for the selected color set and the Attribute Editor displays with the polyColorMod node tab selected.
The color modifications you make on the polyColorMod node are cumulative. Normally, you should apply color modifications to either the HSV global modifiers or the RGBA color channel modifiers.
