3D Modifier - Change the opacity of the geometry vertices using an input attribute
Same as Colorize Function
Colorize all vertex of the geometry using a and a 3D MaskRead More but only to control opacity. The mask and gradient parameters are
replaced by the unique function Opacity.
In combination with 3D Mask3D masks enable selecting 3D vertices based on their different attributes such as position, color and texture coordinate.Read More, this can do powerful stuff.
Opacity (3D Mask) : Opacity function to apply to all vertices of the geometry.
