 ## Mesh: Vertex Group Bleed
 
-The Smooth operator with "Expand" tends to either clip values or smear them way too much, which is not always what you want. Bleed provides finer control and guarantees that new weights will never be lower than the input weights. Works in your favor when you want to create a clean weight gradient radiating from an edge loop, or to soften skinning without  weakening the overall deformation.

-Can sort of think of it like pathfinding, running the operator twice with the same parameters won't change the results.
