This shader is a custom lighting solution designed to simulate anisotropic specular highlights in Unity. It allows full control over the shape, color, and intensity of the highlight, based on the angle between the main light and the camera. The effect can be selectively applied using a mask, making it especially suitable for materials like hair, brushed metal, or fabrics.
