Vertex Map Falloff

The Vertex Map falloff converts values of the currently selected Vertex Map to values representing falloff strength. While generally a Weight Map is used, being the most intuitive approach, you may also use values of other Vertex Map types as a falloff as well. The falloff is determined by the values of an existing Vertex Map. This allows you to create complex falloffs that actually can have a inverse negative in instances where negative values can be applied.

If a user chooses "Component" for the 'Mode' option, the falloff tool uses the component value specified by the index option. For example, if the current map is a Morph Map and the index is X, then the falloff sets the X value of morph position to the weight value. Magnitude is effective for morph, RGB, and RGBA maps. If the current map selected is a morph map, the falloff returns the length of the morph delta position. If it is RGB or RGBA, the falloff returns the luminosity of color vector.

Mode	The following falloff modes are available: • Magnitude - Values of the Vertex Map are converted to strength values and applied to the affected surface(s). • Component - You can select individual components of a map: Weight Map (1 component- weight value), RGB Map (3 components- R, G or B), RGBA Map (4 components- R, G, B or A), Morph Map (3 components- X, Y or Z), Pick Map (1 component).
Index	When Component mode is selected, you can determine the specific component using this option selector.
Mix Mode	In instances where there are multiple falloffs applied to a transform (using the Add option of the Falloff menu), the mix mode defines how each falloff interacts with the other.
