Pixelation Occurring – How to make higher quality?

[empireofryan]

Followed along the previous video & this one and did a render at the ~7:35 mark. The procedurally generated landscape looks neat but the quality is not very high. I can see a lot of pixelation, especially yellow squares. Since we touched so many parameters throughout this process, can you tell me where this pixelation is coming from and how to make the image more ‘high-res’?

That’s a really cool displacement result so far! Those yellow squares are common “sampling artifacts” of Cycles and path-tracing renderers in general. The first thing I recommend trying is enabling clamping in the Light Paths settings: Increasing from zero to 10. If 10 doesn’t improve, try 5.
