In the first picture it seems the virtual surface of the normal map is calculated to behind the camera. I only have this bug on convex surfaces.

However in both these pictures it seems the surface of the normal map is floating above the original texture. It duplicates the surface instead of replacing it.

I really don't know what's going on here.

    \$\begingroup\$ It's hard for us to diagnose the issue given only two stills. Can you please include the textures you're using, and show us how you've configured your material or shader? \$\endgroup\$

    \$\begingroup\$ I'm voting to close as unclear until we have more information on the textures and shader. ^ \$\endgroup\$ Jun 6 '17 at 12:26

    \$\begingroup\$ It doesn't look like you've imported your bumpmap as a normal map, following the steps in the docs here. Can you check whether the problem persists after you change the Texture Type to Normal Map, check Create From Grayscale, and click Apply? Or are you trying to use it as a displacement map? \$\endgroup\$

    \$\begingroup\$ You've referred to a bump map a few times in your post but appear to be suggesting it's actually a height map. Could you double check the references to a bumpmap are accurate? There's currently three of them. \$\endgroup\$ Jun 6 '17 at 13:33

    \$\begingroup\$ Have you tried disabling reflections? That's what it looks like its trying to do. \$\endgroup\$ Jun 6 '17 at 13:37
