4.8 procedural foliage spawner starter tutorial

Actually, it’s the grass that’s spawning incorrectly, not the foliage. Foliage is behaving as expected. It’s the grass that is not working. I’m using the grass output node in my landscape material and it is spawning the grass objects I choose. It’s just spawning them all in a flat field at the bottom of the landscape’s bounding box. It is respecting the painting done, only spawning where I have painted the apropos layer, just not at the proper Z height. I don’t see anything in the grass material or grass object that defines a Z offset. Am I missing a hidden flag somewhere?
