Typical Workflows

Understanding how Leonardo.Ai works is best illustrated through its typical workflows, which demonstrate its versatility for different creative needs. From concept art to game asset creation, the platform streamlines many traditionally time-consuming processes.

Workflow 1: Rapid Concept Art & Ideation

This is perhaps the most common way artists leverage Leonardo.Ai. Imagine a game studio needing to visualize new character designs or environmental concepts quickly.

Prompting & Initial Generation: An artist starts by entering a descriptive text prompt, such as “futuristic cyborg warrior, sleek armor, glowing eyes, dystopian cityscape background, cyberpunk style, octane render.” They select a relevant AI model (e.g., “Leonardo Creative” or a community-trained cyberpunk model) and adjust parameters like aspect ratio and guidance scale.
Iteration & Refinement: Leonardo.Ai generates several variations. The artist reviews these, selects the most promising ones, and uses them as image-to-image inputs or refines the prompt. They might add negative prompts (“ugly, deformed, blurry”) to steer the AI away from undesirable elements.
AI Canvas for Composition: If a generated image has a great character but a limited background, the artist can move it to the AI Canvas. Here, they can expand the canvas, prompt the AI to generate more background elements, or even remove unwanted objects using inpainting. This allows for dynamic composition adjustments.
Upscaling & Export: Once satisfied with the concept, the image is upscaled to a higher resolution for presentation or further work in traditional art software. This workflow dramatically cuts down the time spent on initial sketches and mood boards.

Workflow 2: Game Asset Creation (Textures & Sprites)

For game developers, how Leonardo.Ai works can significantly accelerate asset production, especially for 2D sprites or 3D textures.

Texture Generation: A developer needs a seamless “scifi metal floor” texture. They input this prompt, specify “seamless texture” in the prompt, and select a model known for architectural elements. Leonardo.Ai generates several seamless options.
Fine-tuning & Detail: The developer might use the AI Canvas to add specific details, like “worn scratches” or “grime,” by painting over areas and prompting the AI to generate those elements.
Sprite Sheet Creation (Indirect): For 2D games, an artist might generate individual character poses or items. While Leonardo.Ai doesn’t directly create sprite sheets, it excels at generating consistent individual frames. The artist can then use their custom-trained model (see Workflow 3) to generate variations of a character in different poses from a base image. These individual images are then compiled into a sprite sheet using external tools.
Export & Integration: The generated textures are exported in high resolution, ready to be applied to 3D models in game engines like Unity or Unreal Engine, or individual sprites are prepared for 2D animation.

Workflow 3: Custom Model Training for Brand Consistency

This advanced workflow is crucial for studios or individuals needing a consistent aesthetic across many assets.

Data Collection: The artist gathers a dataset of 10-20 high-quality images representing their desired style, character, or object. This could be concept art for a specific game, character sheets, or a collection of unique item designs.
Model Training: They upload these images to Leonardo.Ai’s custom model training interface. They give the model a unique identifier and let the platform train a new AI model based on their input. This process fine-tunes a base model to understand and replicate the specific visual language of the provided dataset.
Generating with the Custom Model: Once trained, this custom model becomes available in their generation settings. Now, when they prompt, they select their custom model. This ensures that all generated images, regardless of the prompt, adhere to the aesthetic and style learned from their training data. For example, if they trained a model on their game’s unique character art, every character generated will naturally fit that game’s style.
Iterative Improvement: The artist can continue to refine their custom model by adding more training data or adjusting training parameters over time, ensuring it evolves with their project’s needs.

Workflow 4: Marketing & Promotional Art

Marketing teams also find value in how Leonardo.Ai works for creating compelling visuals quickly.

Ad Creative Generation: A marketing specialist needs striking images for a new game launch. They use prompts like “epic fantasy battle scene, cinematic lighting, dramatic angle, promoting ‘Dragon’s Ascent’ game.”
Style & Branding: They might use their custom-trained model (if they have one for their brand’s visual identity) or select a public model that aligns with their marketing campaign’s aesthetic.
Image Editing & Text Overlay: Using the AI Canvas, they can adjust the composition, add or remove elements to make space for text overlays, or even generate specific graphic elements based on prompts.
Variations for A/B Testing: Leonardo.Ai can quickly generate multiple variations of an image from slightly altered prompts, allowing marketing teams to A/B test different visuals for ad campaigns efficiently.

These workflows demonstrate that how Leonardo.Ai works isn’t just about generating pretty pictures, but about integrating AI into a broader creative pipeline, offering tools for every stage from initial ideation to final asset production.
