How do you rotate a texture in a firefly or superfly material? I was trying out an old  item I have with newer textures (Maclean's Home 1) when I noticed that the woodgrain on the texture I was trying to apply was 90% to what it should be for the prop I was putting it on. I'm  pretty sure there is a way, but for some reason I havent been able to find it in the Poser manual or Renderosity forums.

The easiest way is to turn it in any (free or not) external program such as XnViewMP, which exists for Windows 7+, Mac 10.13+ and Linux
I'm often using external programs and stored the updated pics near the others, for example for the electronic devices, etc...

In the node with the texture, switch uv to vu and it should help.

May I recommend the free Irfan View ??

It continues to evolve and, IMHO, has a friendlier UI...

Note XNView will access Alpha ('Transparency') channel of some formats that IV cannot yet. IIRC, neither XNView nor IV can batch-extract Alpha channels...

But out of interest if you say wanted to rotate a texture 45 or 30 degrees or whatever, I imagine that requires adding texture math nodes of some sort. Which one would you use and where would it go?

Rotation of textures involves a bit of vertex math, but it is not impossible. You do have to use cycles nodes to do so, as far as I know.

This is one way you can rotate a texture, without moving the object. https://b3d.interplanety.org/en/rotating-texture-by-nodes/

This example is shown using the Tile node, but it can equally well be applied to the U and V offset inputs of an image node. The angle is set by Value_1 of the Math_Functions_4 node (45 degrees here). Note that your image would need to be tiling for most uses.
