Material - Normal map

Simple material with Normal map, per pixel specular reflections

This material allows surface rendering with roughness and reflections. Normal map creates curvature on surface and may as well hold inside alpha-channel saved Black&White map limiting specular reflection locally (multiplying values specular[]={R,G,B,A} )

Irradiance table replaces here setting specularPower
