Need Help in Realistic Texturing!

Hi! I am new to blender and I decided to check out some tutorials. I found this in Blender Guru. It’s about creating realistic textures. I followed everything in there but unfortunately, I didn’t get results I was hoping for. My final render included some STRANGE BLACK THINGS. Here is a picture:


That only appears when I start adding the displacement modifier.

Can someone help me? Any help will be much appreciated.

You need to make sure you have enough geometry in the mesh for it to displace properly.

Well, that fixed my problem. Thanks mate!
