I’m trying to import an .obj file into ROBLOX, it doesn’t work, whatever way I try. I have tried using Asset Manager (with separate parts needed), it says “Failed retrying in () seconds”. I have also tried using a mesh part and importing it in, that just gives me the link to the troubleshooting website, I’ve tried these solutions and they don’t work.
It could be that your .obj file has too much poly like Blaaz mentioned or the name of you .obj could be blocked. I remember making mushrooms and named it shrooms.fbx and it wouldn’t upload for that reason, if those don’t change anything I can only advise to restart Studio or try using custom character import.
