Unity HDRP Skill

High Definition Render Pipeline configuration for high-fidelity graphics in Unity.

Overview

This skill provides capabilities for configuring and extending Unity's High Definition Render Pipeline, enabling ray tracing, volumetric effects, and AAA-quality graphics.

Capabilities

Pipeline Configuration

Configure HDRP Asset quality settings
Set up frame settings and render features
Manage diffusion profiles and materials
Configure volume framework

Ray Tracing

Enable ray-traced reflections and GI
Configure ray-traced ambient occlusion
Set up ray-traced shadows
Implement path tracing for offline rendering

Volumetric Effects

Configure volumetric fog and lighting
Set up atmospheric scattering
Implement volumetric clouds
Create god ray effects

Material System

Create HDRP Lit materials
Configure subsurface scattering
Set up fabric and hair shaders
Implement decal projectors

Lighting

Configure physical light units
Set up area lights and line lights
Implement sky systems
Configure reflection probes

Prerequisites

Unity 2021.3+ with HDRP package
DirectX 12 / Vulkan capable hardware
For ray tracing: RTX 2000+ or equivalent

Usage Patterns

HDRP Material Setup

csharp
// Configure HDRP Lit material
var material = new Material(Shader.Find("HDRP/Lit"));
material.SetFloat("_Metallic", 0.8f);
material.SetFloat("_Smoothness", 0.9f);
material.EnableKeyword("_NORMALMAP");

Volume Configuration

1. Create Volume (Global or Local)
2. Add Volume Profile
3. Add overrides (Fog, Exposure, etc.)
4. Configure priority and blend distance

Best Practices

Use physical light units for realistic lighting
Profile ray tracing performance early
Create LOD settings for volumetric effects
Use HDRP Wizard for project setup
Test on target hardware frequently

How this skill was measured

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 24 cases were attempted. The headline lift of +4 percentage points is the difference between those two pass rates over the 24 comparable cases. 1 case got worse with the skill loaded, and it is included in that figure.

Prompt

What technique within HDRP provides ultra-high quality photorealistic rendering for film or non-realtime frames without pre-baked lightmaps?

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
