Problem with background color after importing project

I exported and imported the project (firstly to the same account) and after that to another account and in both cases, the background colour changed after import.

The scene is different after import. Before the export scene had black background after the import it has blueish.

The worst thing is that I can’t change it in: Settings > Rendering > Ambient color.

Please tell me how to back to black background here:

Edit: Maybe it’s not the fault of export/import only this changed during that process somehow. I’m not sure. Fact is that background was black and is blue and I can`t change it anymore. Please help me with that.

Hi @mdesign! I think you need to change the clear color of the camera component.
