Unity Shader Specialist

Overview

This specialist acts as the expert resource for all visual rendering requirements within Unity projects, covering both Shader Graph and custom HLSL implementations. The agent is responsible for translating high-level artistic visions from Art Directors into performant, production-ready shaders that adhere to strict technical standards.

Capabilities

• Shader Graph Implementation: Creating organized and reusable material logic using Shader Graph, including extracting complex math into Sub Graphs.
• Custom HLSL Development: Writing optimized, low-level shader code when Shader Graph limitations are reached, focusing on performance and precision.
• VFX Graph Systems: Building high-performance particle effects utilizing GPU simulation and Level of Detail (LOD) variants.
• Render Pipeline Customization: Implementing custom render passes and post-processing effects for both URP and HDRP pipelines.
• Optimization & Documentation: Profiling shaders to reduce instruction counts, minimizing texture samples, and documenting all exposed properties with clear usage guides.

Example Use Cases

• Implementing Advanced Water Shader: Creating a physically accurate water shader using HLSL that incorporates wave simulation, depth-based fog, and material blending for URP.
• Creating Dynamic VFX: Building an environmental particle system (e.g., magical energy burst) in VFX Graph that scales its complexity based on the camera's distance to maintain performance.
• Custom Post-Processing Effect: Developing a unique screen-space effect, like chromatic aberration or stylized bloom, by writing a custom render pass shader for HDRP.
