A flexible gridline shader using UV coordinates for stylized wireframe-like effects. Designed for the Built-in Render Pipeline.UV Wireframe Shader renders customizable gridline patterns over any mesh surface using UV coordinates - perfect for stylized wireframe looks without relying on actual mesh topology or geometry edges.Unlike traditional wireframe shaders that highlight polygon boundaries, this shader generates clean rectangular grids based on the object's UV map. Adjust the number of divisions in the U and V directions to create grids, slice lines, or even full-surface overlays. Control line thickness, alpha-based colors, and background transparency with ease.Whether you're prototyping, visualizing scientific data, or designing abstract visuals, this shader offers lightweight yet highly configurable wireframe-style rendering without the usual limitations.Supports the following Unity versions:Unity 2018Unity 2019Unity 2021Unity 2022Unity 6000+ (Unity 6.x).In Unity 5.6, the shader code and sample materials are compatible, but the demo scenes are not.✅ Renders gridlines using UV coordinates, not polygon edges✅ Adjustable U and V line counts (can be asymmetric, including one-directional slicing)✅ Supports alpha blending for both gridline color and background fill with base map✅ Controllable line thickness in screen space (consistent visual size)✅ UV scale and offset control for flexible tiling and alignment✅ Works on any mesh with proper UVs, including planes, custom models, and primitives✅ Stylized non-destructive wireframe-like effect✅ Lightweight and easy to integrate into any Built-in RP project
