Overview
Summer’s AI art generation is designed as a prototyping and placeholder tool for game developers. We’re upfront about this: AI-generated art is perfect for rapid iteration, concept exploration, and getting your game playable quickly, but it’s not a replacement for the unique creativity and intentionality that human artists bring. When to Use AI Art:- Early prototyping and concept validation
- Placeholder assets during development
- Rapid iteration on visual ideas
- Learning and experimentation
- Final production art for your game
- Unique artistic vision and style
- Character design with personality and depth
- Marketing and promotional materials

Writing Effective Prompts
Basic Structure
Start with the main subject, then add details about style, mood, and composition:Examples
Character SpritesStyle Presets
Each style is optimized for different game genres and aesthetics:Realistic
- Best for: Modern games, simulators, realistic environments
- Characteristics: Photorealistic rendering, detailed textures, natural lighting
- Example: “Realistic brick wall texture with subtle wear and weathering”
Cartoon
- Best for: Family games, mobile games, casual titles
- Characteristics: Bright colors, simplified shapes, friendly appearance
- Example: “Cartoon treasure chest with golden coins spilling out”
Anime
- Best for: JRPGs, visual novels, character-focused games
- Characteristics: Stylized proportions, vibrant colors, expressive features
- Example: “Anime-style magical girl character with flowing blue hair”
Pixel Art
- Best for: Retro games, indie titles, 2D platformers
- Characteristics: Sharp pixels, limited color palettes, nostalgic feel
- Example: “16-bit pixel art sword with glowing enchantment effect”
Low-Poly
- Best for: Mobile games, minimalist aesthetics, performance-focused titles
- Characteristics: Flat colors, geometric shapes, clean edges
- Example: “Low-poly mountain landscape with simple geometric trees”
Fantasy
- Best for: RPGs, adventure games, medieval settings
- Characteristics: Magical elements, medieval themes, rich details
- Example: “Fantasy spell book with glowing runes and leather binding”
Advanced Features
Prompt Enhancement
Summer can automatically improve your prompts using AI:Original: “A sword”
Enhanced: “A gleaming medieval longsword with ornate crossguard, leather-wrapped grip, and polished steel blade reflecting light, fantasy RPG style”
Enhanced: “A gleaming medieval longsword with ornate crossguard, leather-wrapped grip, and polished steel blade reflecting light, fantasy RPG style”
Reference Images
Upload reference images to guide the style and composition:- Style Reference: Match the artistic style of an existing image
- Composition Reference: Use the layout and structure as a guide
- Color Reference: Extract color palettes from reference images
Regeneration Options
- Regenerate: Create a completely new version with the same prompt
- Refine: Make subtle adjustments to the current result
- Variations: Generate multiple versions to choose from
Asset Metadata
When creating assets, provide detailed information for better discoverability:Required Information
- Title: Clear, descriptive name for your asset
- Asset Type: 2D Image, Texture, Sprite, UI Element, etc.
- Tags: Keywords that help others find your asset
Optional Details
- Description: Detailed explanation of the asset and its intended use
- License: How others can use your asset (Free, Commercial, Attribution, Contact)
- Visibility: Public (visible to all) or Private (only visible to you)
Best Practices
For Game Sprites
- Specify the intended use: “for 2D platformer game”
- Include pose/direction: “facing right, idle pose”
- Mention transparency needs: “on transparent background”
For Textures
- Always specify “seamless” or “tileable” for repeating textures
- Include resolution hints: “high resolution”, “detailed”
- Mention intended surface: “for stone walls”, “metal armor texture”
For UI Elements
- Specify the UI context: “game menu button”, “health bar design”
- Include state variations: “normal, hover, and pressed states”
- Mention size considerations: “scalable vector style”
For Concept Art
- Set the scene: “wide landscape shot”, “character portrait”
- Include mood descriptors: “mysterious”, “heroic”, “peaceful”
- Specify viewing angle: “from below”, “bird’s eye view”
Common Issues and Solutions
Blurry or Low-Quality Results
- Add “high quality”, “detailed”, or “sharp” to your prompt
- Try regenerating with a more specific style preset
- Use reference images for better guidance
Wrong Style or Aesthetic
- Be more specific about the art style you want
- Try different style presets
- Include negative prompts: “not cartoon style” or “avoid realistic rendering”
Unwanted Elements
- Be specific about what you don’t want: “no text”, “no people”, “clean background”
- Use composition terms: “centered”, “isolated object”, “simple background”
Inconsistent Results
- Save successful prompts for reuse
- Use reference images for consistency
- Create variations of working prompts rather than starting over
Integration with Projects
Generated assets can be used immediately in your Summer projects:- Direct Import: Assets are automatically available in your project browser with clear “AI-Generated” labels
- Prototype Workflow: Perfect for rapid prototyping and testing gameplay mechanics
- Batch Generation: Create multiple related placeholder assets with consistent styling
- Transition Planning: Summer can help you identify which AI assets to replace with human art later
Pro Tip: Use AI art to get your game playable quickly, then gradually replace key assets with human-created art as you approach release. This hybrid approach lets you validate your game concept without upfront art costs.
