I have been really busy over the last month with this 2D animation college course and sorry for the late reply.
What I did was duplicate the actor and adjust the actor scale; then in the grass texture that I chose I added that into the foliage. But this comes up with a lot of gray bubbles. It might be the variations and will try when I have time.
PS: I can make a video which might be the best way to tell what I am doing wrong.
How do I set an actor to a foliage? It seems to only want models.
