So my stadium chair that i made earlier Stadium Chair
https://www.cgtrader.com/profile/models
has been sold 3 times on CGTrader. But the site gave me a score of 5.9 saying some stuff, including saying i need to provide more file formats.
i have OBJ and FBX. What else should i provide?
Congradulations on your sales. 
I use a lot of STLS. You could check out the list of file types that blender can import/export if you’re looking for more ideas. (The blue one is only the one I hovered over to keep the list open)
i know the file types. i just want to know which ones people expect or use the most…
obj and fbx are the most widely used formats with the highest compatibility.
I don’t really understand why people rate you down because you only offer the most popular formats and nothing else.
These people are lazy and entitled IMHO.
But you could easily add Gltf and USD as additional formats.
.blend files too.
