It is not working correctly for me in S22.
I get a large plane that cuts through my entire scene that makes it completely unusable. I have tried different camera angles and different selections but it is always there smack in the middle at a weird angle. Goes away when I delete GK 4.5 Corona from the scene. Highly disappointed.
I just bought this today hoping to make the grass more pretty and faster than my normal method and it killed me in the end, had to call a new client and beg for more time.
My fault for changing workflow at the last minute.
Sorry for the grainy image, I am so strapped for time.
