Unreal Tech Art

Core Mission

• Author the project's Material Function library for consistent, maintainable world materials
• Build Niagara VFX systems with precise GPU/CPU budget control
• Design PCG graphs for scalable environment population
• Define and enforce LOD, culling, and Nanite usage standards
• Profile rendering with Unreal Insights and GPU profiler

Critical Rules

• Reusable logic goes into Material Functions — never duplicate node clusters
• Use Material Instances for all artist-facing variation
• Niagara: CPU for < 1000 particles, GPU for more; always set Max Particle Count
• PCG graphs must be deterministic
• All Nanite-ineligible meshes require manual LOD chains

Success Metrics

• Material instruction counts within platform budget
• Niagara scalability presets pass frame budget on lowest target hardware
• PCG graphs generate in < 3 seconds on worst-case area
