This shader showcase demonstrates advanced shader development across Unity and Unreal Engine, integrating tools such as ShaderGraph, VFX Graph, Niagara, Material Editor, and direct HLSL coding.

Accomplishments:

Unity — ShaderGraph & VFX Graph:
Created a wide range of shaders and particle systems using Unity's node-based tools. Developed procedural materials, interactive surfaces, and dynamic lighting effects, achieving consistent results across both Built-in and URP pipelines.

Direct CG / HLSL:
Wrote and optimized custom shader code in HLSL for real-time rendering control. Implemented custom lighting models, post-processing effects, and GPU-efficient materials, demonstrating solid expertise in graphics programming and low-level rendering.

Unreal Engine — Niagara & Shader Systems:
Developed real-time particle and environmental effects using Niagara, integrating GPU simulations, dynamic emitters, and motion-driven visuals. Combined Niagara with Material Editor to create reactive, procedural, and emissive effects with real-time feedback.

Unreal Engine — Material Editor & Native Shader Tool:

Utilized Unreal's Shader Tool and native shader compilation system to integrate custom HLSL code directly into materials. Created advanced shaders for refraction, motion feedback, stylized rendering, and cross-platform optimization (SM5, Vulkan, DX12). 

 Optimization & Cross-Platform Porting

Specialized in optimizing real-time rendering performance across multiple platforms — from high-end PC and PCVR builds to mobile and standalone VR (Meta Quest 3) — while maintaining maximum visual fidelity and stable framerates.

Performance Engineering:

Implemented advanced optimization techniques, including:

• LODs with crossfade transitions, ensuring seamless visual quality while reducing vertex load.

• GPU Instancing and Material Instances to minimize draw calls and memory overhead.

• Batch control and culling strategies to optimize scene complexity without sacrificing detail.

• Texture streaming, reduced overdraw, and shader variant management for consistent GPU performance.

 PCVR → Quest 3 Pipeline:

Successfully ported high-fidelity PCVR content to Meta Quest 3, preserving quality and performance at 90 FPS+ under standalone constraints.

• Leveraged Vulkan and OpenGL ES rendering paths for platform-specific optimization.

• Re-authored shaders and materials for mobile-tier GPUs, maintaining lighting, reflections, and post-effects.

• Optimized particle and shading systems, balancing GPU cost and visual clarity.
