i guess it depends on your number of materials or how wide of an area it covers or something. he didnt give any more clarification really. but there's a reason that worlds use cutout for grass instead of transparency (transparency is "5x" slower than opaque)

either way you also don't spend download size or vram if you do it through shapekey rather than alpha masks

imagine using a 4k alpha mask to hide your ass under your shorts instead of weight transferring properly and moving a couple verts on a shape key
