Hi, I didn't quite understand the essence of your question. Here's some information that might potentially serve as an answer ;).
The materials I used in the demo materials are not included with the addon, and unfortunately, you cannot use them. However, I may add a few free my SD materials to the addon in the future ;).
You can certainly use the BAM Automat addon for your personal project and distribute the materials installed or configured using BAM Automat even if you plan to make a whole materials library ;). (but I won't refuse a minimal mention, although it's not necessary).
Hello, may I use this texture for my own project to sell or not? Thanks for your attention :D
