# Vertex colors as vertex weights

Vertex weights can be used to tell the reduction which parts of the mesh that are important and which are not. Weights can also be used when baking materials, or rather to change the size of the UVs which will affect how much texture space gets used for given parts of the mesh. An example where weights can be applied is when you would want to preserve details on a character, such as nose and eyes.

Creates a ReductionPipeline that will use the specified color-set as vertex weights.

    Sets the strength (multiplier) of the weights.

      Sets the color component to use as weights.

        The weights color mode (previously interpreter) can be used to change the interpretation of weights.

        0 Black: reduce more | White: reduce less
        1 Black: unchanged | White: reduce less
        2 Black: reduce more | White: unchanged

        Sets the weights color mode.
