Hello Blender Artists,
I have recently had this issue with my final renders turning out pixelated while my viewport renders are clean. I can’t figure out my issue. Ive had this issue with any scene. The image I attached is a geo node point cloud setup.
In the viewport screenshots, you are heavily zoomed in on a small render region. When you are in camera view, any zooming that you do with the scroll wheel doesn’t affect the final render, it’s only the camera’s borders that do. The render region also doesn’t affect the size of the render, it only limits which parts of it are skipped.
Ok right. Well why is my final still pixelated. Even if I zoom out in my viewport it is clean.
The single viewport render you have here has good quality because you are zoomed in. This gives the small area more pixels.
If you say it’s better than the final render even when zoomed out, I’m thinking you probably have a monitor with very high resolution. If that’s the case, it’s possible that the viewport has more resolution than your final render.
I totally understand know and see what you mean. My monitor is very high res btw. What do you think I should do to make the entire render the res of the zoomed in shot?
Well, the only way is just to increase the render resolution really.
If you can’t, or if you want your render to be viewable on a lower resolution monitor, you could instead review your point cloud. Use fewer points but make each one bigger. That way, they could be seen clearly on a lower res render.
Ok I appreciate it. My current resolution is pretty high at 3840X1920 100%.
Maybe something else that could help is to set a “min samples” value manually in the render settings (like 100 or so). The noise threshold could easily be missing the very small dots if they are smaller than a pixel and give you messed up anti-aliasing.
Also, go to the render settings → film → pixel filter, and try playing with the filter width. This affects how crisp or blurry the render is. The default of 1.5 makes the render slightly blurry, it’s a strong anti-aliasing. A value of 1 has no blur, just the basic AA. Anything under 1 becomes more and more pixelated.
Thanks for your help good to know.
