Render mode suddenly looks different/worse

Hello! I am newer to Rhino and am having an issue with render mode in perspective view. On Thursday I was working on this model and I took a screenshot of the perspective viewport in Rendered mode and it looked great (see attached). Then today I opened the same file and made a few edits to the model but didn’t change any other settings as far as I’m aware but now it looks like this (see attached in Rendered mode which is much uglier! Can anyone help what settings might have gotten accidentally tweaked to cause this?


your objects may be partially changed by SetObjectDisplayMode, you can clear that by selecting all the geometry, running the command without selecting any of the options and hit enter/space. also the lighting has changed, in your first image the lighting is most likely set to ambient occlusion, it looks like its set to default here now.

it could also be that you moved or copied some objects to a different layer plus some lighting issues. difficult to say from the images,

In the renderpanel, try to reset the render settings.
