I have a hexagon in the Polygon node I would like to rotate so the pointy side is upwards. Applying the rotation nodes, however, simply changes the color of the hexagon from white to a color in the rainbow.
What does the Vector1 of the Polygon output represent and is there a way I can rotate it as if it were a texture?
What does the Vector1 of the Polygon output represent
It represents whether the current pixel being shaded is inside (1) or outside (0) the polygon.
and is there a way I can rotate it as if it were a texture?
Just like with a texture, you don't rotate the colour value coming out of the node. You have to rotate the sample coordinates going into the node.
Here's one way to do it, putting a Rotate node between UV0 and the Polygon node:
Or you can just swap the X and Y axes of your input coordinate:
