Well now it looks a bit better and is tied into draw distance to add more planes when set to the higher distances. Our artists definitely what to make better art for all plants, but that is more like A21.
A big part of it was separating the collision mesh from the visual mesh as this change describes:
"Optimized grass collider generation (Always 2 centered, fixed size and axis aligned planes)."
More complicated grass meshes do not need a more complicated collision mesh and their collision meshes should not stray into adjacent blocks like they did.
It does that too for the mesh. On the higher grass distances, you don't have 2 planes in a + pattern. It is 3 is an overlapping triangle.
And this: "Increased grass mesh variations to 192 (image, scale, rotation, cross/ring)."
