Why Doesn't Submission Like .obj Files?

[hopper13]

How are you exporting the model in AssetStudio?

Going into asset list, clicking on the name of the mesh file I want to check it's the right one, then right-clicking said name then clicking "export selected assets". In the game I'm talking about here, the character textures are stored as texture2D files, but I could possibly be doing something wrong

Thanks for the other points though- quite helpful to a noob such as myself!
