What happened to the carpet? Why is the render messing up the pixels and stuff? Someone, please tell me how to fix this. I'm using Cycles render.

  • $\begingroup$ looks like a lot of noise. Are you using Cycles? then you might need to use a denoiser. $\endgroup$ Apr 13, 2022 at 22:35

I think you need to enable Denoising. Go to Render Properties/Viewport and enable Denoising. Then go to Render Properties/Render and enable Denoising also. I hope this is helpful.


I am assuming you are using Blender 3.0 and above, well they are using a new way to render in cycles and intersecting geometry will have this issue like the carpet so what you can do is select the carpet and move it up by a very small amount like 0.001 m or even smaller.

enter image description here

And also cycles renders with interiors are known to be very very noisy so to deal with that, You can use the denoiser if it is a still image you need but if its a animation you may have to increase the Amount of samples until the noise is barely noticeable.
