3D textures in Poser would be useful. I have seen Youtube videos by a man who seems good at making walnut furniture (real, not CGI). For me to imitate this in CGI in Poser would need 3D textures, to get the grain correct at the various faces of the cut piece of wood.
The 3D texture could be a Python script which, if told the x/y/zTranslates and x/y/zRotates and x/y/zScales and Scale of where the piece of wood is assumed to be within the original walnut tree log, will calcuilate at any point (u,v,w) the red/green/blue color values of the wood at the point (u,v,w).

Photographic textures look the best when used with the right shaders. I made a shader that does what this Blender shader does but I'm guessing you still use Firefly for rendering. https://www.youtube.com/watch?v=V3wghbZ-Vh4

here is a link to my shader.

I want to say these shaders are high quality and equal or better than many commercial products. Thank you for your shaders, ghostship2.

OP was on 3d textures, not on photographic ones.
I can only agree. I still miss the power of good old PovRay script language where you could set the relationship between geometry and texture in the transformations via the sequence of the commands.

The OP wants "real" looking wood textures with grain i.e. bump/normal/displacement. IMO the best textures are photograph based.

The only photo realistic wood texture including end grain is to take a real life block of wood, trim it, sand it, finish it to the shape that you need, image it and map your images on the geometry. Any other solution looks like cheap plastic coated board or, at best, veneer. Of course in all this your uv map should be strictly un-stretched.
Yes, good 3d procedural wood textures are hard to come by, but they are the only way to image wood properly.
