ARKit - Adding texture to object in Scene Editor

Question

This would be working perfectly if it weren't for one aspect of what is going on. When I add the texture to the object (drag and drop it onto the object from the menu in the bottom right) it adds it exactly where I want, but it also adds it around the object large (too large for the object) and all blurred, and I want it to just stay white:

Before:

After:

I want it to stay in the middle where it is, and have the surrounding area be the original color of the shirt.

UPDATE

I created a static physics body, and that allowed me to get to the materials of the Plane object. But I can't remove the coloring around the image.

UPDATE

Also, I exported the texture from Blender with Save Image As from Blender UV/Image Editor, I'm not sure if that is the correct way to export a texture to be used correctly in xcode.

UPDATE

I used the .obj file instead and got this far, but when it renders in the app there is no image, only they gray tshirt.

To export a .dae including textures from Blender, make sure to select UV Textures and the Copy checkbox unter Texture Options, in the Export options, during export. Then, in xcode, your texture will be available as a material under the Materials tab, and you just have to drag the image that you were using with the texture, onto the material (make sure you have the correct material selected) in the Scene Editor in Xcode.
