That is really a great thing for us all. http://fewhacks.com/
I just based my landscape material on this. I just wish I could exactly figure out what is going on with normals, ao and displacement here.
That was extremely helpful! Thank you!
Texture Artist Vinicius Ribeiro has presented a metal pack for Textures.com with more than 20 high-quality substances that you can download right now. The materials can help you polish your hard surface works or perfect sci-fi scenes.
This was a long project that I did in partnership with Textures.com, our goal was to increase the amount of metal substances in the site library bringing the highest quality materials! I learned a lot during the whole process and feel that I evolved as an artist! All materials were made completely procedural, except for two of them, in which I used some bitmap images as source.
Not all materials are available on the site, but you can download some of them, check out the library, it’s worth it!
You can find the metal substances here.
