Weird renderings


the render I do comes out like this:


What can I do???


Hi -

Provide more information.
Can you post the 3dm file? Which renderer are you using?
Run the Rhino SystemInfo command and copy-paste the result here.

That looks like maybe you have the Intel denoiser enabled and have achieved very few samples. Check the post effects section of the Render window. The tiled repeat of the whole scene though is very odd so provide more details when you can.

Thank you both, here is the systeminfo:

Here is a link to the file.

Also, I am using the ProRender.


Update: ok so when I increase the DPI and quality the issue doesn’t remain. I managed to create a good render.

Thank you!

I’m glad you found a setting change that helped solve the issue. I checked in with the developer and updating to of ProRender via the PackageManager should also get rid of those artifacts. Since you don’t have an AMD GPU in your Mac, ProRender is using the CPU which may not be faster than just sticking with Rhino Render. The Intel denoiser in my experience will still need a minimum of 50 - 100 samples depending on the scene too. If you have fine textures in materials, make it 250 - 500.
