Bump map not applying at all I've been trawling through the web for 2+ hours on this issue, determined to find the answer instead of creating a new thread - but I can't seem to find a solution that will work for me at all. 

I've applied a normal map to the plane that acts as a table, but no matter what I do I cannot get it to raise up or down. I've attached both a screenshot from the 3d viewport + node view, and the final render as well. 

Any help would be greatly appreciated!! 

P.S I've been following this guide: https://www.youtube.com/watch?v=izqZe8s_Jmw
You should really plug your normal map into both the Diffuse and Glossy node, however, that's not why you are seeing no effect.

The normal map you are using is basically flat. You can see this by looking at it in the UV Image Editor. It's from a glossy surface with virtually no variations in surface depth. You will simply not see much, if any, effect from that normal map.

To contrast, look at the normal map you are using (basically all one colour) and then look at this (randomly selected) one I found on Google from a brick surface that has a lot of variation: http://jsoverson.github.io/texture.js/demo/images/brickwork-normal.jpg
