Does anyone know what's going on here? I plopped in a couple Dune grass object (great go-tos, thanks Ulco) populations, and I immediately noticed something odd. I got these weird shadows on the classic erosion heightmap at a distance. Up close, everything seems fine. It almost looks like the hard shadow things are hugging the flows.

Any ideas?
