I'm modeling our church sanctuary to assist in a lighting design and I am reusing a procedural wood material from the wood pews to kind of simulate the laminated beams that hold up the roof, but those beams are vertical, not horizontal like the pews.
I've tried just adjusting rotation in the vector transforms, and I've tried switching the scaling to favor the z-axis rather than the x-axis. Neither attempt has worked.
(This procedural wood is courtesy of an old thread on blenderartists.org)
The horizontally striped beam is the test beam (on the right, in the light)
