Draft scene loses realism and reflections

1

hello
There is some reason why metallic and shiny objects again lose shine and appear dull, everything that has some shine in the roughness channel appears flat and dull.

This happens in the following situations:

  1. Editing in the cloud, then closing the scene to continue editing later, you open the scene again and it has already lost all its shine.

  2. once you finish editing in the cloud, and the draft is published, when you open the already published scene, the same thing happens, it loses all the brightness and realism that could be seen when it was being edited

I attach images of the quality of the scene while editing in the cloud and images of the scene once published,

please help me

images during editing, before publishing the draft

Thanks for the detailed description. The issue is not related to the draft/published scene version, but to the sky being in HDR format. Shapespark doesn’t generate reflection probe images for HDR skies properly. When you added the sky texture there was no change in the reflections, because reflections probe images are not regenerated immediately. Only when you reloaded the scene (after publishing), the new reflection probe images were computed, with reflections being way too dark. We’ll be looking into this issue.

For now, please change your sky from HDR format to LDR format (jpg, webp), and the reflections should have proper strength.

Ok, perfect, thank you very much for the help, it worked.

It’s a shame that we can’t put the sky in HDRI, do you know if this would happen anyway if the scene is baked in the desktop version, would the same thing happen when uploading it?

Yes, until we resolve the issue the reflections from a HDR sky will be dark no matter if you add the sky in the desktop or cloud editor.

Hi ,

Its been a while and this issue remains, is there any solution or any tip to avoid it? greetings

I am sorry, the light probes taken with an HDR sky texture still generate reflections that are too dark. However, as suggested previously, if you use a JPG or WebP version of the HDR sky, the reflections will be brighter. Furthermore, JPG/WebP format is recommended for sky textures to reduce the scene size.

Do you have an JPG/WebP version of your sky texture?
