As you can see in the image below, the lid on a jam of jar I modeled seems to distort whenever I put the mesh into cycles rendering. Then, when I put it back to material preview, it goes back to normal. Please help me fix this. Thanks! :)

  • $\begingroup$ @brockmann I don't believe so, except for maybe a subdiv... but that isn't actually on the lid itself. $\endgroup$ – MmmChezBurgerz Jun 17 '20 at 10:05

    $\begingroup$ Did you plug something into the displacement input of the "Material Output" node (the last one) in your shader editor ? $\endgroup$ – Gorgious Jun 17 '20 at 10:06

You need to make sure there is nothing plugged into the "Displacement" output of your material shader. Alternatively you can also disable the true displacement within the material properties, but this might leave the artifacts as a bump.
