I'm having an issue that whenever I input a normal map into a shader normal node in blender 2.9 it disables smoothing for that object and the polygon face edges become visible in the render.
Any idea why?

$\begingroup$ If any of the objects were baked with shading set to flat then that will be on the normal map as well $\endgroup$– Mr ZakApr 21, 2019 at 14:17

Here's a question: which is more high-res, your object, or the normal map? If the object is more high-res, than the normal map is going to hide that with it's low-res faces.

It ended up being a packing issue, when I unpacked the normal map into an external folder it worked.
