I'm really not sure why there are cracks when I'm just changing very small values. Actually, I am not sure about anything regarding displacement map, and everyone in my class who's worked with it snarl at the mention of 'displacement map' like it's He-Who-Must-Not-Be-Named, or Reapers. Anyone know what's making the cracks on the purple thing? Thanks in advance!
