3D Asset Optimization Assistant
Optimize 3D game assets with polycount reduction, LOD planning, and performance predictions
What You Can Do
You can analyze complex 3D meshes and receive specific polycount reduction strategies that preserve visual fidelity for real-time game engines. The skill generates complete LOD hierarchy specifications tailored to your target platform (mobile, VR, console, or PC), calculates performance impact across hardware tiers, and provides documented optimization decisions for team consistency and technical reviews.
Features
identifies geometry-preserving techniques to hit target budgets
creates 3-5 level-of-detail variants with specific topology and vertex targets
balances resolution, compression, and quality loss across platforms
estimates frame impact, memory usage, and VRAM allocation for different hardware
generates technical reports and decision logs for team alignment
quantifies visual fidelity loss and suggests mitigation strategies
tailors optimization for strict performance constraints
Example Output
Input: Character model - 125,000 polygons, targeting mobile
Output:
- LOD0: 32,000 polygons (baked normal maps for detail retention)
- LOD1: 12,000 polygons (merged minor geometry)
- LOD2: 4,500 polygons (simplified skeleton, removed accessories)
- Estimated GPU impact: 2.1ms → 0.7ms per frame (60fps target)
- Texture strategy: 2K diffuse + 1K normal → 1K diffuse + 512 normal
- Quality loss: 8% visual difference in close-ups, imperceptible at distance
Input: Environment asset - establishing optimization guidelines
Output:
- Building LOD specs: 45K → 18K → 6K polygons
- Vegetation culling distances and LOD swap thresholds
- Draw call reduction plan (material atlasing recommendations)
- Performance headroom allocation across mobile GPU tiers

You can automate asset validation across your game development pipeline by feeding Claude asset metadata, export logs, and pipeline documentation. Claude analyzes each asset against your studio's specific standards and produces detailed reports with prioritized compliance issues, naming violations, geometry problems, and material setup errors—complete with remediation steps for each flagged item. This eliminates manual review bottlenecks and ensures consistent quality before assets reach production environments.

You can systematically isolate shader issues by feeding Claude compilation error logs, frame captures, and pipeline diagnostics. Claude analyzes root causes across vertex, fragment, and compute shader stages, identifies rendering artifact patterns (z-fighting, normal map issues, texture corruption), and pinpoints GPU performance bottlenecks. This replaces manual trial-and-error debugging and frame capture tool grinding with structured problem diagnosis.

You can model complex game economies to detect systemic failures, simulate long-term player spending across 6-12 month lifespans, and identify second-order effects like inflation cascades, retention cliffs, and whale dependency. Claude processes interconnected currency flows, progression pacing, and monetization mechanics to generate optimization recommendations grounded in player behavior theory.

You can systematically diagnose constraint hierarchy conflicts, IK solver failures, weight painting errors, and deformation artifacts without access to your DCC viewport. This skill generates root-cause analysis, targeted remediation steps, and verification protocols to resolve constraint popping, asymmetrical deformations, pole vector inversions, and blending discontinuities—accelerating your rig debugging workflow.

You can submit pixel art sprites for detailed technical and aesthetic critique, receiving structured feedback on animation consistency, palette violations, anti-aliasing artifacts, and visual continuity. Claude validates technical specs, identifies optimization opportunities, and helps translate stakeholder feedback into actionable art direction—streamlining your sprite refinement pipeline from rough iteration to production-ready assets.
