TRY THIS:Create a simple SPHERE in the bottom left corner of your screen, and use your materials to colour it RED (without changing the material name)Use OBJECT - NEW to open a NEW object page - the red sphere will disappear - no problem - just go to the OBJECT menu and select Object01 and you'll see it again.Use the OBJECT menu and return to Object02 page, and create a new CUBE in the top right corner. Use materials to colour it ORANGE (without changing the material name)Select the CUBE and use CONTROL-C to copy itGo to OBJECT01 and use CONTROL-V to paste the cube on the sphere's page.
