7. Generate Your Asset Catalog

- You can select multiple assets or even entire folders directly in your Project Files.
For more detailed information on what asset you can use, see the Selecting the right assets page.
2. Right-click the selection and choose Generate Catalog
.

3. Add a description.
- This should include key details about the assets’ style, theme, and intended usage.
Let an LLM do the writing for you!
Paste your asset pack URL into your favorite chat interface and use this prompt:“Analyze every item in the catalog and write 3-5 sentences (60-120 words) that capture their shared stylistic and technical DNA. Cover dominant art styles/eras, modelling techniques, color palette and lighting mood, and any typical functional contexts. Omitting all file paths, IDs, prices, or seller names.”
Having issues with catalog generation?
If you’re using a free Gemini API key, it may be due to rate or token limits.👉 See common solutions here
