Hey! I’m very new to Blender, I just started learning yesterday from the Noob to Pro book in fact. I’m sorry if the following question seems stupid.
The render that you see above is plagued by those black spots. I have no idea where they came from. Some searches brought up Non Manifold points which are indeed present since I was able to select them. But I have no idea how to fix them. I tried recalculating the normals. Could someone please explain?
Also, how did I manage to do this? Anyway to prevent it from happening again?
