Overview

• The Contour Line Shader is a powerful shader designed for the Built-in 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.
