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
(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):
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
Before you ask, yes I have quadruple checked that the material is applied.
Thank you very much for any help.
