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)?

  • Does this answer your question? How to use 2.8's default HDRi's in renders? – Emir May 22 '21 at 17:15
  • If you look at "Sampling" in your scene properties, you can see one difference, which is that you are using many fewer samples in the viewport. So the viewport will have more rendering artifacts (sometimes called fireflies.) Another major difference is that you are using a denoiser in your render but not in the viewport. – Marty Fouts May 22 '21 at 17:29
  • @Emir unfortunately, no – kuksu May 22 '21 at 17:29
  • @MartyFouts thank you, I did some changed and updated the post. Deleted denoiser and also increased viewport sampling, it looks the same. All render settings attached – kuksu May 22 '21 at 17:42
  • For me it looks like you have an HDRI for the render preview, but no HDRI for the Final Render, that's why I suggested the answer to add a world HDRI. There is basically no reflection on the final other than the floor and wall – Emir May 22 '21 at 17:42
  • @Emir where to check on that? I've got it in my World Properties (surface-background, color-hdri) also scene lights and scene world options checked – kuksu May 22 '21 at 17:46
  • can you attach the blend file so we can look at it? – Marty Fouts May 22 '21 at 17:55
  • @kuksu Sorry, this is a good tutorial about it video – Emir May 22 '21 at 17:59
  • @Emir thank you, I watched this and everything is right, so this is still unsolved.. – kuksu May 22 '21 at 21:29
  • @MartyFouts just attached a file in post, hopefully there will be some kind of answer – kuksu May 22 '21 at 21:30

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

Diamond1 in render but not viewport

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

disabled in render

Viewport

viewport

Render

render

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