ChromaStage: TEV-Style Combiner Shading

Recreate early-2000s console visuals in Unity 6 URP. ChromaStage emulates GameCube TEV with 2-stage combiner, parallax, emission, and toggleable Stage 1 additive tint for retro magic auras.

• Render Pipeline: Built exclusively for the Universal Render Pipeline (URP) in Unity 6.
• 2-Stage TEV Combiner: Emulates the GameCube's Texture Environment unit. Stage 0 handles base texture and lighting math, while Stage 1 is a toggleable additive color blender.
• Stage 1 Additive Tinting: Enable Stage 1 to blend PREV + KONST0 (previous result + constant color). Perfect for creating magical auras, energy effects, or unified environment tints in a single pass.
• Retro Specular System: Dedicated Specular Mask slot paired with an adjustable Shininess slider for sharp, stylized light glints on metal and plastic surfaces.
• Parallax Height Mapping: Built-in Height Map slot that provides fake 3D depth on surfaces without the heavy performance cost of Parallax Occlusion Mapping (POM).
• Emission Support: Dedicated Emission Map slot with an adjustable Intensity slider for creating glowing neon signs, magic projectiles, and sci-fi elements.
• Lighting Constants: Built-in controls for Shininess and Ambient Boost to fine-tune the stylized look.
• Custom C# GUI: A clean, custom Material Inspector designed to make configuring TEV stages and properties intuitive.
• Demo Scenes Included: 3 fully built showcase scenes (Feature Breakdown, Character Showcase, and Retro Environment) demonstrating the shader on various assets.

Bring the iconic, stylized look of the 6th generation of consoles to your Unity project.

The ChromaStage: TEV-Style Combiner Shader is a custom, lightweight shader designed to replicate the fixed-function graphics pipeline of the GameCube. Instead of relying on expensive, modern physically based rendering (PBR) calculations, this shader uses authentic TEV-style color blending math. This makes it incredibly performant while producing that signature retro aesthetic.

Key Features:

• 2-Stage TEV Blending: Stage 0 handles the base texture and lighting math. Stage 1 is fully toggleable and performs an additive color blend (PREV + KONST0), allowing you to inject constant colors for magical glows, energy effects, or unified environment tints.
• Retro Specular System: Features a dedicated Specular Mask slot and adjustable Shininess slider to create sharp, stylized glints on metal and plastic.
• Parallax Height Mapping: Add fake 3D depth to your surfaces without the heavy performance cost of Parallax Occlusion Mapping (POM). Perfect for retro brick walls and rocky surfaces.
• Emission Mapping: Create glowing neon signs, magic projectiles, and sci-fi energy cores with the dedicated emission map and intensity slider.
• Lighting Constants: Built-in controls for Shininess, Ambient Boost, and Stage 1 toggles.
• Unity 6 & URP Optimized: Built specifically for the Universal Render Pipeline in Unity 6, ensuring modern performance and compatibility.

Perfect For:

• Retro PS1/GameCube-style games
• Low-poly stylized projects
• Developers looking for high performance on mobile or lower-end PCs
• Creating magical/energy effects using the additive Stage 1 tint

Package Contents:
