Building Grass Map toast stays up forever

The Building Grass Maps toast stays up forever when your landscape material does not have a landscape grass output and the landscape option Bake Material Position Offset Into Collision is checked.

Adding a landscape grass output into the material will remove the toast.

We are not 100% sure if we need that landscape grass output node for the bake material position offset into collision to work.

1. Create a simple landscape material (See image)
2. Create a simple landscape
3. Apply the material to the landscape
4. With the landscape selected check Bake Material Position Offset Into Collision

Result: Building Grass Maps (64) toast appears and the number never changes.
