Render different than render preview I've got a problem with rendering this scene. What I get, looks totally different compared to render view, with these options turned on, also changes in light paths, setting bounces etc. doesn't seem to affect anything.
What did I do wrong? Is there something in the Render settings, Preferences, or my computer (worst option, hopefully not)?

EDIT:
You have a fourth diamond, called &quot;Diamond1&quot; in your scene.  You have it enabled for render but not for viewport shading:

When I disable it from the render, the two match as closely as can be expected:

Viewport

Render

The remaining difference is because there are more samples in the render than the viewport.
