So I have never really used blender before and now I need to change a model file from glTF to OBJ for my After Effects project, but the model in blender doesn't show up. (I'm sorry if this like a dumb question.)
I got the model from https://sketchfab.com/3d-models/apple-iphone-15-pro-max-black-df17520841214c1792fb8a44c6783ee7
(The .glTF file it was WinRar zip.)
