Nasty Artifacts When Following Tutorial
Hello everyone. I have been following a tutorial on how to make rocks. I've followed it perfectly, yet I'm still getting really bad artifacts on my curvature. I checked every setting at least a dozen times. My normal looks perfect and the graph isn't even that complicated. What is going on here!? Tutorial:… -

Thank you. Lowering the resolution fixed it. Not sure why that happens. Anyways, I ended up using a very intense blur node. It's wasn't exact to the tutorial, but i got the general idea. -

It was 16bit. It just doesn't like high resolutions. -
Re: Nasty Artifacts When Following Tutorial
Could be a conflict between normals set to Open GL and DirectX. Make sure your material and the nodes are all set up to the same. Another possibility is that you've plugged the normal node too late in the chain where you've already added a lot of surface noise. edit: also make sure you're in 16 bit mode and check how it… -

It looks like a quantization problem. Make sure all the nodes before the height to normal node are set to compute in 16 bits per channel. Also, if the graph is based on an imported bitmap, make sure that bitmap is 16bpc as well. -

I haven't seen anyone suggest it but you could also try Curvature Smooth. -
Re: Nasty Artifacts When Following Tutorial
You could try to scale down the normal node locally beforehand, run through the curvature, plug into a levels node and scale that up again. Might perhaps work better then the blur workaround.
