I downloaded this here: https://free3d.com/3d-model/cartoon-rocket-878331.html.
But when i import the obj to blender all the materials are black. I searched for a solution on web allready but nothing seems to work here. Thank you for your help.
Did you check if each part does have its own separate material, even though they’re all black? In that case you can easily change each material into a standard Blender material and set the colors.
In the worst case scenario you can still select parts and assign materials to them yourself.
yes every part has its own material. thank you for the tip
