AI Game Asset Polish: Fix Flat Sprites, Tiles, Icons
Find out why AI game sprites, tiles, and icons look flat at in-game size, then fix them with ordered value, palette, light, and edge passes.
Before & after
Same prompt, same agent — the only difference is the skill.
AI-generated assets can sometimes look basic or lack detail. There are a few approaches you could take. You might try re-prompting the generator with more detailed descriptions. Some people use post-processing tools like Photoshop or GIMP to add shading and highlights. You could also look into upscaling the images or using style transfer techniques. There are some online tools that do this. Manual touch-up work might help too. Have you tried any enhancement tools before? It really depends on your art style and the level of quality you need.
GAME ASSET ENHANCEMENT WORKFLOW Fable 5 Enhancement (20-minute turnaround per sprite) STEP 1: SOURCE ANALYSIS → Input: Flat 256x256 PNG (AI-generated pixel art sprite) → Assess: Current lighting model, color palette, silhouette clarity → Identify: Missing shadow depth, weak highlights, muted contrast STEP 2: FABLE 5 UPSCALING & REFINEMENT → Model: "game-assets-v2" preset (optimized for 2D game sprites) → Prompt: "Add volumetric shadows on character left side, increase rim lighting on edges, enhance color saturation by 15%, sharpen silhouette" → Output resolution: 512x512 (2x scale for crisp details) → Render time: 45 seconds per sprite STEP 3: POST-PROCESS ADJUSTMENTS → Levels: Push blacks to true black (0,0,0), white point to 255 → Hue-saturation: Boost target color by 20% (character's primary color) → Sharpening: Unsharp mask (radius: 1.2px, amount: 120%) → Shadow detail: Add 8% noise to shadow areas for texture STEP 4: EXPORT & INTEGRATE → Format: PNG with transparency, trim excess canvas → File: character-enhanced.png (ready for game engine) → Batch process: Handles 10-15 sprites per session DELIVERY → Before-and-after sprite comparison → Enhanced asset files ready for import → Typical improvement: 40% increase in perceived visual quality
About this skill
Your AI-generated sprites looked fine in the generator. In the game they turn to mush: blurry fake pixels, muddy shading, white halos around the edges, and a set where every asset seems to come from a different game. This skill finds the actual cause at in-game size and fixes it in the right order, so you are not just piling on glow and noise.
What it does
- Tests each asset at its real display size, in grayscale and on your actual background, to find out why it reads as flat
- Rebuilds fake AI "pixel art" onto a true pixel grid and reduces it to a limited, shared palette
- Replaces AI's muddy darken-only shading with hue-shifted ramps and one consistent light source, plus contact shadows and edge outlines
- Repairs alpha left by background removal: halos, stray semi-transparent pixels, and edge color bleed that ruins mipmaps
- Audits a full asset set for drift in texel density, light direction, outline weight, and perspective, then flags assets that need regenerating instead of polishing
- Writes the image-processing script inline (Python with Pillow and numpy) when you are working on files in Claude Code
What you get
A diagnosis for each asset, an ordered fix plan with concrete settings, and a working script when you want automation. You also get a short list of assets to regenerate or paint over instead of polish.
Best for
Indie and game-jam developers who ship with AI-generated sprites, tiles, icons, or textures and need them to look like one cohesive, readable game.
