Is there a specific way ingots and textures are done?

They all seem to share the same noise pattern. I was wondering if they used some template and the colors have just been changed.

The psd file didn't contain anything related to those two inquiries.

Besides that, is that the newest PSD file you have?
Cheers!

PS.: I was planning to at least texture common Gregtech New Horizons items and machines. They are also based on tiers. And all machines in all tiers look the same. It's a pain to play. You have to rely on WAILA.
