nShader

The nShader Gizmo can control lighting and shading of elements in a rendered image.
The nShader Gizmo needs only X, Y and Z normal information.

Normal Vectors : set your Normal Pass
Equator Angle : controls the left to right angle of the light
Polar Height : controls the top to bottom angle of the light
Light Color : set light color
Only Light :  Enable gives you only light impact and disable gives you compose output.
