Good morning, it took 48 hours for all of them to import 3D objects I tried all the ways until I downloaded a 3D zappar object and it works but everything goes black. My 3D objects I have imported into .fbx and I have done all the steps of the tutorial and it does not work, thank you very much to everyone who has a good day.
sorry for annoying I have solved the problems thanks to @seb I have seen a comment from him I could solve about the illumination of the object. Also, thank you very much …
Glad it’s all sorted out, Tito!
