If you would like to learn a bit about the above woods, take a look here.
Houdini has a node that does wooden planks (hooray!), so I'm currently working on modifying that so that the various planks are more random like real wooden planks are. I've put in presets for the various colors to reflect the above woods, just to give the user a starting point. I know that defaults help me figure out how the shader was built and what I am meant to do with it.

Now there are variations within each plank! But the wood grain is very uniform. In the reference photos there are large swatches of variations within the color then sharp lines of darker color on top of that. Now to figure out how to do that!

Blurry/sharp combination acquired! It does make it a little darker overall but I've put in controls so the user can control the levels separately. The mesquite wood has high levels of this blurry mess underneath the darker sharp lines. It also has cracks in the wood which I am going to simulate next.
