AI art creation with ComfyUI and Krita ​

Create stunning AI-powered artwork by connecting ComfyUI's advanced AI capabilities with Krita's professional digital art tools. This guide shows you how to set up your complete AI art workflow with Olares.

Understanding the components ​

Your AI art studio consists of three key pieces working together:

  • ComfyUI: The AI engine running in your Olares environment that powers image generation.
  • Krita: Professional-grade digital art software where you'll create and edit your artwork.
  • Krita AI Diffusion Plugin: The connector that enables seamless communication between Krita and ComfyUI.

What you'll need ​

Before starting, ensure you have:

  • A working Olares installation with internet access
  • A computer connected to the same local network as Olares
  • Sufficient system resources (recommended: 16GB RAM for optimal performance)

Set up ComfyUI ​

  1. Install ComfyUI from Market based on your role:

    • For admin: Install both "ComfyUI For Cluster" and "ComfyUI".
    • For team members: Ensure your admin has installed "ComfyUI For Cluster", and install "ComfyUI" only.

  2. Configure ComfyUI.

    a. Open Settings, navigate to Applications > ComfyUI > Entrances.

    b. Set the Authentication level to Internal. ComfyUI authentication level

  3. Launch ComfyUI from your desktop, and verify the installation by generating a sample image.

  4. Copy the address of ComfyUI for next steps.

TIP

For security, you should always run AI applications within your local network. When properly configured, your ComfyUI URL should contain .local.

If .local is missing, check your local network environment and make sure no external network proxy service is enabled.
