I am currently developing a scene and some assets to work with. 
I'm not using any UV mapping or texturing as I'm going for an old polygonal 90's look. 
So, I have a 'Grass' mesh that I want to use as a tile on the faces of a simple plane geometry. 
I was wondering if there was a way to do this and have the 'Grass' mesh scale to the faces appropriately. I was thinking of just simply Shift-D to duplicate the grass and then place it on the mesh manually, but I would like to know if theres a better way. 

Would be nice if there was a way to just extrude or scale the 'Grass' mesh and have it simply divide its appearance as it scales.
