Description Lit Shader – Advanced PBR and Custom Lighting for Unity URP

Lit Shader is a high-performance, artist-friendly PBR shader for Unity URP designed to make your materials look professional, cinematic, and distinctive.

Whether you’re building realistic worlds or stylized visuals, Lit Shader gives you the control and polish you’ve always wanted — without the complexity of Shader Graph.

Built for Unity developers who want better lighting, faster workflows, and superior results, this shader is your next step up from Unity’s default Lit Shader.

🎨 Why Lit Shader?

Unity’s default URP shader is a great starting point — but it’s limited.

Lit Shader unlocks advanced lighting, intuitive material controls, and performance optimizations that help your scenes pop while staying production-ready.

You’ll spend less time fighting texture packing, guessing exposure values, or tuning roughness maps — and more time crafting the look you want.

⚙️ Core Features

1. True PBR Lighting

Get physically accurate reflections, highlights, and shading powered by a custom-tuned BRDF.

Supports both realistic and stylized looks, adaptable for any art direction.

2. Full Texture Support

Use your complete texture set — Albedo, Roughness, Metalness, Normal, Height, AO, and Emission — directly.

No complex texture packing. Just drop them in and go.

3. Artist-Centered Controls

Each texture input includes exposure sliders, giving artists precise per-texture control over intensity and brightness — perfect for matching your intended look without constant re-exports.

4. Height & Vertex Blending

Blend between materials using vertex colors or height maps to add natural variation.

Create terrain transitions, worn edges, or layered materials without writing custom shaders.

5. Optimized for Performance

Built for speed and scalability, Lit Shader uses shader variant stripping and efficient lighting math to deliver great visuals with minimal GPU overhead.

Ideal for PC, console, or high-end WebGL rendering.

6. Works Natively with Unity URP

Fully compatible with Unity 2022 LTS and Unity 6.

Supports Forward and Deferred rendering paths, reflection probes, and global illumination — ready to drop into any URP project.

💡 Perfect For:

Developers who want to upgrade from the default URP Lit Shader Artists who need custom lighting control without Shader Graph complexity Teams targeting PC and console-quality visuals Stylized or realistic projects needing flexible, polished PBR rendering Environment artists who blend multiple materials (terrain, buildings, props)
