Contour Line Shader(URP)

The Contour Line Shader is a powerful shader designed for the Universal Render Pipeline that visualizes mesh geometry with clean and customizable contour lines. Whether you’re developing stylized environments, scientific visualizations, or data-driven graphics, this shader enables you to display evenly spaced lines along the X, Y, and Z axes of your models with full control. You can enable contour lines along any combination of axes (X, Y, Z), and customize line thickness(screen-space consistent), line interval and coloring options. Set gradient colors based on Zero (minimum) and Maximum contour line positions, and choose whether to base these positions on Local Space (object-relative) or World Space. Line thickness is calculated in screen space, not world space, so the visual width of contour lines remains consistent regardless of zoom level or object scale. Line Options: Line Interval: Adjustable spacing between contour lines, Line Color: Three contour coloring modes, Line Thickness: calculated in screen space, Emissive Mode On/Off. Choose from three contour coloring modes: Gradient between Min and Max line colors, Min Color Only, Max Color Only. The shader also supports: A transparent base color or texture (Base Map), Specular highlights for a polished appearance, Adjustable Zero and Max line positions, Smooth rendering even beyond defined color bounds by clamping to Min/Max colors. With full axis and color control, Contour Line Shader gives you artistic freedom and technical precision—all in one asset. Supports the following Unity versions: Unity 2022, Unity 6000.0 (Unity 6.0), Unity 6000.2 (Unity 6.2), Unity 6000.3 (Unity 6.3). Important: In Unity 6.0 or higher, you must enable the Compatibility Mode in `Project Settings` > `Graphics`
