Import Hatch samples in Rhino

Hi

I would like to import some samples of materials in Rhino.
Is it possible to use your own materials/photo’s? If yes, what kind of format do I have to use?

Thanks!

Hi Marko - not as hatches - hatches are defined by text files with special rules (it’s tedious)- a search on ‘Hatch pattern definition’ will get you started…
