I'm very new to Blender and I am trying to add a concrete normal map to a tower, however while it is visible on the material preview, it doesn't show on the object:
In this image you can see the preview material render as well as my nodes.
The render looks like so:
As you can see, the render doesn't look great - there are visible lines that I assume are needing smoothing, but as you can see my concern is that the bump map is not visible.
Why is this, and how can I get this normal map/texture working?
