Overview

This skill provides practical, production-ready guidance for 3D graphics, shader programming, VFX, lighting and rendering optimization. It packs engine-agnostic patterns for PBR and stylized shaders, particle systems, LOD and batching strategies to create stunning visuals while preserving performance. Use it to implement shaders, tune rendering pipelines, and solve common rendering bottlenecks.

How this skill works

The skill inspects core rendering stages—vertex transformation, rasterization and fragment shading—and supplies concrete shader snippets and formulas for PBR and toon shading. It outlines particle system architecture (emitter → spawn → update → render), common VFX recipes, and optimization techniques like instancing, batching and LOD tuning. Platform guidelines and troubleshooting checklists help adapt complexity and resource budgets to mobile, console, PC and VR targets.

When to use it

• Implementing production-ready PBR or stylized shaders for games or real-time apps.
• Designing particle effects, trails, or billboard-based VFX with predictable performance.
• Reducing draw calls and GPU work for mobile, console, PC or VR platforms.
• Setting up LODs, occlusion culling and instancing for large scenes.
• Debugging shader artifacts, sampling issues or lighting inaccuracies.

Best practices

• Prefer GPU instancing for many identical objects and static batching for non-moving geometry.
• Match shader complexity to platform budgets; keep mobile shaders simple and console/PC shaders richer.
• Use PBR formulas (GGX distribution, Fresnel Schlick) for physically plausible lighting.
• Drive toon ramps or stylized shading with step functions and a separate outline pass.
• Profile draw calls and shader cost; prioritize reducing state changes and texture binds.

Example use cases

• Create a production PBR surface with GGX specular and Fresnel-based reflectance.
• Build a cel-shaded character with stepped lighting and an inverted-hull outline pass.
• Compose fire, smoke, spark and magic VFX using emitter recipes and color-over-life.
• Optimize an open-world scene via GPU instancing for foliage and LODs for distant props.
• Resolve common visual glitches by validating normals, clamping outputs and checking sampler states.
