I've started to learn Blender by myself with all tutos on the web. I really enjoy Blender. First sorry for my english... I have a problem to make a bump on the normal node. So I try witha very simple cube. Il I put a checker on the normal node the cube become b&w and I don't "see" bump.
If I add a normal map node I see the cube grey and white but still no bump...
What have I missed? I have Blender 2.8 and filmic add-on.
Thank you very much for help.
