I created this

material in substance designer and generated the normal map, bump map, and color map and imported it into blender with a node setup like such

enter image description here

(note that I've tried both "Color" and "non-color data" with no difference between the two).

However, I end up with this in the render (zoomed in for detail):

enter image description here

Note that the handle part on the bottom left is lacking a material, and the entirety of the rest of the cup has the material applied. I've noticed that the noise shown is just an artefact of the default render I've set up.

As well, this is further strange because the material shown in the material viewer looks quite alright

enter image description here

Before you ask, yes I have quadruple checked that the material is applied.

Thank you very much for any help.

Turns out I hadn't created a UV unwrap of my model, and thus the texture/heightmap/normal map wasn't being applied.
