Creating Custom Game Icons with ComfyUI: A Complete Workflow Guide

ComfyUI AI Images have revolutionized how game developers create custom artwork, offering powerful node-based workflows for generating consistent character icons and game assets. This comprehensive guide demonstrates how to build a complete icon creation workflow using ComfyUI, showcasing the flexibility and power of AI-generated artwork for game development projects.

🌐 Before You Begin: Why Use Promptus Studio Comfy (PSC)?

Before diving into the technical details, it's worth noting that Promptus Studio Comfy (PSC) stands as one of the leading platforms that builds upon the open-source ComfyUI framework.

Promptus is a browser-based, cloud-powered visual AI platform that provides:

  • An accessible interface for ComfyUI workflows through CosyFlows (a no-code interface)
  • Real-time collaboration
  • Built-in access to advanced models like Gemini Flash, HiDream, and Hunyuan3D

🛠️ Setting Up Your ComfyUI Environment for Game Icon Creation

Getting started with ComfyUI for game development involves several key components:

  • Begin by selecting the right model. For this workflow, use Dream Shaper XL v2.0, a large language model (~6GB).
  • Obtain the model from repositories like Hugging Face or Civit AI.
  • Download and place the model in your ComfyUI/models/checkpoints folder.

🔗 Node-Based Simplicity

ComfyUI uses a color-coded node system:

  • Pink connects to pink
  • Yellow to yellow
  • Red to red
  • Green to green

This intuitive, visual approach makes building complex workflows accessible even for developers new to AI image generation.

⚙️ Building Your Icon Generation Workflow

The core workflow follows a logical process:

  1. Load your LLM model
  2. Feed it into positive and negative prompts
  3. Process through a sampler
  4. Decode using a VAE decoder to produce the final image
  • The negative prompt filters out unwanted elements (text, watermarks, etc.)
  • Consistency in head positioning and sizing is achieved through seed manipulation
    • Example: changing the seed from 2028 to 2027 allows fine-tuning while preserving coherence.

🔤 Advanced Workflow Enhancement with Text Concatenation

One of ComfyUI’s most powerful features is the text concatenate node, which joins multiple text inputs—especially useful with CSV-based style libraries.

🎨 Example: Graffiti Style Prompt

“aerosol art style, bold composition, vibrant colors, urban aesthetic, hip hop”

These can be automatically concatenated into your main prompt, enabling scalable and consistent stylization across hundreds of icon variations.

🔁 Workflow Persistence and Reproducibility

Every image generated in ComfyUI contains its complete workflow metadata inside the PNG file.

  • Simply drag a generated image back into ComfyUI to recreate the exact workflow—including:
    • Prompts
    • Seeds
    • Node configurations

This feature is invaluable for ensuring consistency across character designs, allowing easy edits and regenerations.

👤 Creating Cohesive Character Race Icons

The project successfully generated eight distinct character race icons:

  • Lycibion
  • Stormborne
  • Fireborne
  • Stoneborne
  • Azurian
  • Chrysterian

🚀 How It Was Done:

  • Consistent head position and size maintained via systematic seed manipulation
  • Custom aesthetics achieved using styles like "palette knife" for a hand-painted effect

This approach creates icons that stand out from generic digital artwork and match your game’s unique visual identity.

📊 System Monitoring and Performance Optimization

ComfyUI provides real-time system feedback, including:

  • GPU usage
  • VRAM consumption
  • GPU temperature
  • Disk activity
  • CPU utilization

Monitoring these metrics helps:

  • Optimize batch sizes
  • Avoid system overload
  • Balance quality vs. speed for tight production schedules

🌍 Expanding Beyond Character Icons

These techniques apply beyond icons to a range of game assets:

  • Textures
  • Environmental elements
  • Custom glyphs or hieroglyphs

Use the same prompt engineering and style concatenation strategies to maintain visual consistency across your game world.
