This is the final beta version of the previous model. Where the same approach is already applied, but with more experience. Relatively able to reproduce the texture of gold. If you have a better texture of gold, then better use it.
The main pattern is derived through the normals card. Next, we attach the normal of the texture that we have or have made to the pattern, and we get the desired result. In my case, the picture of the image was of poor quality. If you have a better picture, I would be glad if you would share it.
So that you can easily change the texture, I will leave you a clean file with texture nodes.
