Joined mesh only rendering one part of my texture

I’m currently trying to render a simple texture on a mesh without any lamps or shaders, and I’m using all the same settings I usually use on my successful renders. For some reason this time around Blender is only choosing to render a part of the models texture, leaving the rest black. While all of the mesh is joined as one and the texture is for the mesh as a whole. I’ve tried everything I could think of to fix this problem, but after almost a day of attempts I have no idea what to try next. Below is an attached image of what the render looks like, and my basic texture settings.

Any help would be greatly appreciated, Thank you so much! - render outcome - basic texture settings

If theres any other info needed to understand/help please let me know, I’m very new to this program.
