The Asset Generator creates pixel art backgrounds, props, and UI elements using AI. It shares the same Image Editor pipeline as the Character Designer but is tailored for non-character assets.

Accessing the Asset Generator¶

Click Asset Generator in the sidebar. A project must be active and an AI provider configured.

Asset Types¶

The Asset Generator supports three asset types, selected via the type buttons at the top of the form:

Creating an Asset¶

Step 1: Select Asset Type¶

Click one of the three asset type buttons: Background, Prop/Object, or UI Element.

Step 2: Fill in Details¶

• Asset Name (required) -- A descriptive name (e.g., "Jungle Temple Entrance").
• Description (required) -- A detailed description of what the asset should look like.
• Tags (optional) -- Comma-separated tags for organizing and searching (e.g., "jungle, temple, exterior").

Step 3: Choose Aspect Ratio¶

For backgrounds and UI elements, select an aspect ratio from the available options:

• 1:1 -- Square (default)
• 16:9 -- Widescreen landscape
• 9:16 -- Portrait / tall
• 3:4 -- Near-square portrait
• 4:3 -- Near-square landscape
• 21:9 -- Ultra-wide

Props are always generated at 1:1.

Step 4: Choose a Resolution¶

A Resolution dropdown appears just above the reference image checkbox. The options available depend on the selected asset type:

• Background -- Groups of 4:3 presets (320x240, 640x480, 800x600, 1024x768, 1280x960), 16:9 presets (640x360, 1280x720, 1920x1080, 2560x1440), and Retro Consoles (256x224 SNES, 160x144 Game Boy).
• Prop/Object -- Square options from 16x16 to 256x256.
• UI Element -- Square options from 16x16 to 256x256.

The option that matches the project's resolution default for that asset type is marked with (project default). You can select a different resolution for this generation; the override applies only to the current generation and is not saved back to the project.

Step 5: Use Reference Image (Optional)¶

For Background assets, if an environment reference image has been uploaded in Project Settings, a checkbox labeled Use project reference image appears. Enable this to include the reference image in the generation request for style guidance.

Step 6: Generate¶

Click Generate Asset. The AI generates an image based on your description, the project style guide, and the selected background color. Results appear in the AI Image tab on the right.

Step 7: Process and Save¶

The processing pipeline is the same as the Character Designer:

1. AI Image tab -- Adjust grid size and color count, then click Get Pixel Perfect.
2. Image Editor tab -- Fine-tune the pixel art with palette editing, drawing tools, and the Image menu.
3. Preview tab -- For props and UI elements, set a transparent color and preview with transparency. Backgrounds do not have a preview tab since they are full-frame images.
4. Click Save Pixel Art to save the asset.

Editing an Existing Asset¶

1. Open the Asset Browser and click on an asset.
2. Click Edit Asset in the detail popup.
3. The Asset Generator opens in edit mode with the existing images loaded.
4. Modify the pixel art in the Image Editor tab.
5. Click Update Asset to save changes.

Creating a Variant¶

A variant is a new asset generated from an existing one: the same tree in autumn colors, the same treasure chest but open, the same button in a pressed state.

1. Open the Asset Browser and click the source asset.
2. Click Create Variant in the detail popup.
3. The Asset Generator opens in variant mode:
   • The asset type is locked to the source's type.
   • The name is pre-filled as "Source name Variant".
   • A thumbnail of the source and the label Variant of: … appear below the form.
   • The project reference image checkbox is hidden; the source image is the reference.
4. In Description, write what should change.
5. Click Generate Variant. The source's processed image is sent along with the prompt, so the result stays close to the original.
6. Process and save as usual.

The saved variant is a normal asset with the extra tag variant and a link back to the source asset. Deleting the source does not delete its variants.

Character variants work the same way but open the Character Designer.

Prompt System¶

The Asset Generator builds prompts automatically by combining:

• Your asset description
• The project's style guide description
• The project's background color
• The resolution selected in the form (defaults to the project's Resolution Default for that asset type)
• Asset-type-specific prompt templates (variants use a dedicated template that tells the model to modify the attached reference)

This ensures visual consistency across all assets in the project.
