This guide walks you through creating your first project, configuring an AI provider, and generating your first pixel art asset.
Step 1: Create a Project¶
When you first launch Retro Asset Studio, you will see a welcome screen with a Create Your First Project button.
- Click Create Your First Project (or go to Project > New Project in the menu bar).
- Fill in the project details:
- Project Name -- Give your project a descriptive name (e.g., "Jungle Platformer").
- Style Description -- Describe the visual style you want (e.g., "16-bit adventure game, earthy tones"). This text is injected into all AI prompts to maintain consistency.
- Background Color -- Choose a solid background color for generated images. This color is used behind sprites and can later be made transparent.
- Optionally select an AI provider and enter your API key under API Configuration (this can also be done later from Project Settings).
- Click Create Project.

Your project is now active and visible in the project selector dropdown in the title bar.
Step 2: Configure an AI Provider¶
AI image generation runs through Google Gemini, the recommended and only enabled provider in this alpha. Retro Asset Studio itself is free; Google bills you for the images you generate, and image generation requires a paid Google AI plan. Without a key you can still use the pixel editor, the pose tools, and the spritesheet tools, but you cannot generate images.
- Get a Google AI Studio key at aistudio.google.com/apikey and make sure billing is enabled on the linked Google Cloud project.
- Navigate to Project Settings from the sidebar (or Project > Project Settings in the menu bar).
- Scroll to the API Configuration section. Google Gemini (Image Generation) is already selected.
- Paste the key into the Google AI API Key field and choose a model.
gemini-3-pro-imageis the recommended default. - Click Test Connection to verify the key. This generates one small test image, which Google bills.
- Click Save Settings.
Other providers
Hugging Face and OpenAI are listed in the provider card but greyed out with a "Coming soon" label. They cannot be selected in this version. See AI Providers.
For the settings themselves, see API Configuration.
Step 3: Generate Your First Character¶
- Click Character Designer in the sidebar.
- Fill in the character details:
- Character Name -- e.g., "Adventure Hero"
- Description -- Describe appearance, clothing, and key features.
- Style Notes (optional) -- Additional style direction.
- Click Generate Character.
- Wait 10-30 seconds for the AI to produce an image.
- The result appears in the AI Image tab on the right side.
Step 4: Process the Image¶
The AI output is a high-resolution image. You need to convert it to pixel art:
- In the AI Image tab, adjust the Grid size slider so the grid lines align with the visible pixel boundaries in the image.
- Set the Colors slider to the number of palette colors you want (e.g., 16 or 24).
- Click Get Pixel Perfect to snap the image to a pixel grid and quantize colors.
The result opens in the Image Editor tab where you can fine-tune the pixel art.
Step 5: Save Your Asset¶
- Review the pixel art in the Image Editor. Make any touch-ups with the pencil or eraser tools.
- For non-background assets, set a Transparent Color in the palette sidebar and click Generate Preview to see the asset with transparency.
- Click Save Pixel Art at the bottom of the panel.
Your asset is now saved and visible in the Asset Browser.
Step 6: Explore Further¶
From here you can:
- Generate backgrounds and props using the Asset Generator.
- Pose your characters with the Pose Editor and save animation frames.
- Generate a whole animation at once with the Spritesheet Generator.
- Build spritesheets in the Spritesheet Editor and export them for your game engine.
- Browse and manage all assets in the Asset Browser, or create a variant of any of them.
- Back up your project with File > Export Project… (see Project Management).
The Menu Bar¶
The title bar contains the application menus:
| Menu | What it holds |
|---|---|
| File | Export Project…, Export All Projects…, Import Project…, Exit |
| Edit | Undo, Redo |
| Project | Project Settings, New Project, Close Project |
| Image | Mirror, move, scale, and resize commands. Appears only while the Image Editor tab is active. See Image menu. |
| Help | About Retro Asset Studio: shows the installed version and links to the website, this documentation, the bug tracker, and the Ko-fi page. |
When you report a bug, copy the version number from the About dialog.
Understanding the Workflow¶
Describe Asset → AI Generation → Pixel Snap → Palette Edit → Save
↓
Pose Editor / Spritesheet Generator → Save Frames
↓
Spritesheet Editor → Export PNG Strip
The typical workflow flows from generation through refinement to export. Each stage gives you full control over the output.
