Did you get it from the 3D viewer because I’m pretty sure that won’t work. If you’re looking to import your own asset then you should build one in an external software like Blender or Maya and the file type matters as well (like OBJ.) and you would also have to texture this asset.
I think perhaps the issue is that it’s taken from the 3D viewer. If you’re interested in making it or fixing this issue you could try to make it in blender, texture it then upload it to roblox. If you’re stuck follow a tutorial.
I hope this helped
I tried and it still doesn’t work. Just took a look in output(since I tought to take a look there but roblox is tsaying that the name is inappropriate the file was called “borden”). Thanks for your help, this topic is solved.
