New to texturing, looking for a good guide/help

Apologies if I’m in the wrong area and if this question has been asked before. I’m newish to texturing in blender, can someone reccomend a good place to start? In short i have a faint idea on wat some maps do, but dont fully comprehend how to utilize them, and im working with texture sheets that wont let me repeat a certain section.

Thank you for your time.

It’s hard to understand the question. :thinking:
I think it would be good to write down specific problems.
It is easy to understand if you attach the image.
