YimingWu f8f7c0ca6d GPencil: Fading based on distance to reference object in Opacity and Thickness modifiers
This patch allows you to dynamically control stroke's opacity and thickness using an object for distance reference in the modifier. Fading range is adjustable, and it is compatible with current curve/vertex group selection.
