How do I fix layer blend normal issue?

[anonymous_user_070be1711 (Jokerofalltrades)]

I’m in UE version 4.6.

I want blend my rock textures in with my sand but I get a issue blending when I add a normal map. It works fine without it.

Here it is without a normal map:

and here is the Material for it:

Now here is the scene with the normal map:

I used the same sand texture for both so it should match up like in the first picture. There appears to get something wrong with my normal but I’m not sure what.

Thanks.
