can't import obj from photoshop in dimension

your screengrab is a shape turned into a basic 3D object by a system called 'extrusion'... they are simple and not good for decal work

what went wrong? = 2 things;

1. you did not generate a Uv map in Photoshop before exporting it... that is why it looks like more than 1 thing
2. you made the shape from a smart object... this locks the textures

if you go back into Photoshop and correct these two mistakes it will give you a much better result but you will still be able to see the small join mark from the extrusion at some angles so if the object is going to be say a glass sitting on a table with the sun behind it then I'd make the model in Blender, Wrap or Maya instead

I can add that the problem is the export from photoshop. it exports not one file it makes different ones...???
