# FAQ & Disclaimer
**Are these assets AI-generated?**
No. Every single asset in ZenShaders Library, including materials, textures, decals, sculpt brushes and generators, is created manually and procedurally in Substance Designer. No AI image generation tools are used at any stage of production. Everything you see is hand-built node by node.
***
**Can I use ZenShaders assets to train AI models?**
No. The license explicitly prohibits using these assets to train, fine-tune or generate images with any AI or machine learning model. This applies to all formats included in the library.
***
**Can I use these assets in commercial projects?**
Yes. The royalty-free license covers both personal and commercial use with no additional fees.
***
**Do I need to credit ZenShaders?**
No credit is required, though it is always appreciated.
***
**My download contains multiple .zip files. How do I install them?**
Some categories are split into several parts due to their size.
Example using Blender\_ZenShaders\_Brushes:
1. Download all the 4 parts and make sure all the parts are in the same folder. (IMPORTANT: Please do not rename the downloaded parts. It's okey if they look like blank files)
2. Install a compression tool. We recommended to use 7Zip.
3. Right-click on the first part named: "Blender\_ZenShaders\_Brushes.zip.001" and unzip it. You just need to unzip the first part.
4. After the unzip is done you should now have a folder named: "Blender\_ZenShaders\_Brushes" and the folder's size should be 15,4gb.
5. Follow the guide named: "Blender installation guide.txt" to finish the installation.

```
GET https://zenshaders.gitbook.io/zenshaders-docs/faq-and-disclaimer.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
