Hi Maxim, I’m new here. So you have already tried adding a compositing tag to Schuppe.1 and turned off shadows for the main object which turned off all the shadows for the clones? I tried recreating it and didn’t see any issues. You could maybe try making the cloner editable. Or in your lights under Project, you can Exclude your main object. Hope this helps or you find a solution. Good luck!
