Normalmapping that reacts to sunlight is actually a standard use. The complex things come when linking it too lights.

This is due to the fact that the sun is defined in the shader with a keyword thus the compiler and eventually the engine links it with it

The HLSL code for generating the normal map effect (which I gave you in the previous topic) is capable of interacting with the sunlight.

I actually don't see any problem.
Sunlight is actually considered to be a dynamic light in A7 but I guess you can always make it static by not moving it and setting the light range to a high range.

Try adding that shader again and set one light which completely lits the needed area

Thanks in progress
