Gemini Texture Generator for Blender

Blender add-on that:

• calls the Gemini image API from a panel inside Blender
• lets you enter a prompt
• stores the API key in Add-on Preferences
• opens the Google AI Studio API key page from a button
• has a clearly labeled free model preset and a protected paid model preset
• supports Seamless, Free, and fixed 1024x1024 generation modes
• shows a preview of the generated texture
• generates helper Normal, Roughness, and Metallic maps
• applies the texture to selected faces or the active object
• has Apply + Create UV If Missing
• uses BOX projection plus Cube Projection
• can resize the generated texture to 512, 256, or 128
• saves generated textures and maps to a local output folder

Important

The plugin defaults to FREE - Gemini 2.0 Flash Image (gemini-2.0-flash-preview-image-generation) when that model is available for your Google AI Studio project.

PAID - Gemini 2.5 Flash Image / Nano Banana (gemini-2.5-flash-image) can charge your billing account. The plugin requires an extra confirmation checkbox before using this paid model.

Free quotas, model availability, and billing requirements are controlled by Google AI Studio / Gemini API and can differ by account, region, project, and current Google policy.

Install

1. In Blender open Edit > Preferences > Add-ons > Install...
2. Select the gemini_texture_generator folder after zipping it, or package it as a zip first.
3. Enable the add-on.

Use

1. Open View3D > Sidebar > Gemini Tex.
2. Open add-on settings in Edit > Preferences > Add-ons, find this add-on, and enter the Gemini API key there.
3. Optionally use the Get API Key button in Add-on Preferences.
4. Enter the prompt for the texture in the sidebar panel.
5. Choose the model preset. Use FREE - Gemini 2.0 Flash Image unless you intentionally want the paid Nano Banana model.
6. Enable Seamless if needed.
7. Choose 1024x1024 or Free.
8. Click Generate Texture.
9. Review the preview.
10. Click Generate Maps if you want helper normal, roughness, and metallic textures.
11. Click Apply To Selection/Object or Apply + Create UV If Missing.
12. Use 512, 256, or 128 to resize the current generated image set.
13. Use Save Locally to save the texture set to the configured output folder.

Notes

• Default model preset is FREE - Gemini 2.0 Flash Image.
• The paid gemini-2.5-flash-image preset is protected by an extra confirmation checkbox.
• If you change the model to a Gemini 3 image model, the add-on also exposes the 1K/2K/4K quality selector in Free mode.
• Helper maps are generated locally inside Blender from the base texture, so they do not require extra Gemini requests.
• If the current .blend file is saved, output files are stored in Textures next to the .blend file.
• If the current .blend file has not been saved yet, the add-on falls back to ~/BlenderGeminiTextures or the folder set in Add-on Preferences.
• Gemini image generation capabilities and model names are documented at: https://ai.google.dev/gemini-api/docs/image-generation
