Krita, the beloved open-source digital painting application, has evolved significantly with the integration of AI generation capabilities. One of the most powerful ways to enhance your AI art creation in Krita is by expanding your sampler options. These samplers—the algorithms that guide how AI generates images—can dramatically influence your artistic results. Let's explore how you can add more samplers to Krita's AI tools and take your digital art to new heights.
Samplers in Krita's AI generation tool are specialized algorithms that control how the diffusion process works when creating AI-generated art. Each sampler has unique characteristics that affect image quality, generation speed, and artistic style. The default samplers provided with Krita's AI tools are just the beginning—expanding your sampler collection can give you significantly more creative control.
When working with Krita's AI tools, samplers determine how noise is gradually transformed into coherent images through a process called diffusion. Different samplers can produce variations in detail levels, color accuracy, and overall aesthetic quality. Understanding these differences is crucial for selecting the right sampler for your specific artistic goals.
Each sampler in Krita's AI tools suite offers a distinct approach to image generation:
DDIM: Offers a good balance between speed and quality
Euler: Creates smoother transitions and is excellent for portraits
DPM++: Provides enhanced detail preservation, ideal for complex scenes
UniPC: Delivers faster generation with comparable quality to slower methods
The impact of choosing different samplers becomes particularly noticeable in detailed areas like facial features, textures, and complex patterns. Experimenting with various samplers can help you discover which ones best match your artistic vision.
Before adding new samplers, ensure your Krita AI plugin is properly configured:
Verify you have the latest version of Krita installed (5.2.0 or newer recommended)
Check that the AI diffusion plugin is correctly installed and activated
Make sure your system meets the hardware requirements (CUDA-compatible GPU with at least 4GB VRAM recommended)
Having a stable foundation ensures that new samplers will integrate smoothly with your existing workflow. Remember to back up any custom settings before making changes to your AI tools configuration. 1
To expand your sampler options in Krita's AI generation tools:
Locate your plugin directory: Navigate to your Krita installation folder, then find the AI diffusion plugin folder (typically under plugins/krita-ai-diffusion/
)
Access the samplers folder: Within the plugin directory, locate the samplers
or configs
subfolder
Download compatible samplers: Visit the official Krita AI diffusion GitHub repository or community forums to find additional sampler configurations
Install the new samplers: Copy the sampler configuration files (usually .yaml or .json format) into the samplers directory
Restart Krita: Close and reopen Krita to allow the application to recognize your newly added samplers
For more advanced users, you can also modify existing sampler configurations to create custom variants tailored to your specific artistic needs. This approach requires some understanding of the underlying parameters but can yield highly personalized results.
Once you've added new samplers, you may want to optimize their performance:
Adjust step count: Higher step counts generally produce better quality but take longer to generate
Modify CFG scale: Control how closely the generation follows your prompt
Experiment with scheduler types: Different schedulers (like linear, cosine, or exponential) can complement specific samplers
Balance performance and quality: Some samplers like UniPC or DDIM offer faster generation at comparable quality
Finding the right balance between generation speed and image quality is crucial, especially if you're working on hardware with limited resources. Some samplers are specifically optimized for faster performance while others prioritize image quality.
When working with custom samplers in Krita's AI tools, you might encounter a few challenges:
Compatibility issues: Not all samplers work with all models; check compatibility documentation
Performance problems: Some samplers require more VRAM or processing power
Unexpected results: Different samplers may interpret prompts differently
Plugin conflicts: Other Krita plugins might interfere with AI generation
If you encounter errors after adding new samplers, try reverting to default samplers to isolate the issue. The Krita community forums and the plugin's GitHub page are excellent resources for troubleshooting specific problems.
Advanced users can leverage multiple samplers in sequence to achieve unique artistic effects:
Use a detail-oriented sampler like DPM++ for initial generation
Switch to a sampler that excels at color harmony for refinement
Apply a final pass with a sampler known for enhancing specific features
This multi-sampler approach allows for greater control over different aspects of the generation process, resulting in images that combine the strengths of various algorithms.
To streamline your creative process, consider creating preset combinations of samplers and settings for different types of projects:
Portrait preset: Samplers that excel at facial details and skin textures
Landscape preset: Samplers that handle complex natural scenes and lighting
Abstract art preset: Samplers that produce interesting patterns and color relationships
Concept art preset: Balanced samplers that generate clear, detailed compositions
Saving these presets allows you to quickly switch between optimized configurations without needing to adjust multiple settings each time.
