Realistic wood grain textures

this question is about wood textures. we are modeling in rhino for our pergola configurator—struggling with a realistic wood grain texture— nothing is looking good— looking for tips, tricks or wood grain textures that have been found to to yield realistic wood grain

There are several questions which may help others:

  • Which version of Rhino are you using?
  • Which renderer are you wanting to use?
  • Are these supposed to be static images or is there an interactive tool which is used on the internet?
  • Must they take certain forms? E.g., must they be procedural or can you not just use open-source PBR textures?

what kind of wood are you looking for? How are you mapping your objects? Pls share a model and pictures of what you have achieved so far.
