I have followed Blender Guru's tutorial on modelling the donut, cup, plate and table, however, at some point along the way of getting there something happened. Both in my rendered viewport and when I try to render a picture of all the objects, it all gets blurry. You can see how it is working on the particles in order to render it, but at one point it decides to blur everything. The final render is all blurred up. Could you please help me with this? I tried playing with all the settings, reached 5th page of google looking through forums, but I could not solve it. I am quite desperate. Thank you very much, I really appreciate it. Have a great day!

  • $\begingroup$ It sure looks like a depth of field issue, but I can't find anything wrong with your settings. I'll look for something else. $\endgroup$ Commented Nov 28, 2018 at 21:52
  • $\begingroup$ Well I am stumped for now. I have never seen this. But I found a work around. Just start a new project then append all the objects except for the camera. Then everything worked correctly. $\endgroup$

  • $\begingroup$ Also you had weird scaling (in the negatives) on some of your objects and also be careful you had square samples set to 200 thats 40,000 samples and would take 5 years to render. $\endgroup$

1 Answer 1


Under the film tab you had Blackman-Harris at value 10.00, and the default is 1.50.
