i have a bezier curve. i used geometry nodes to add an object as it's spline. then i created a material which has a wave texture. i was able to use a capture attribute and send that data to the material in order for the wave texture to follow the curve (by watching a default cube tutorial). but what i am trying to do is rotate the texture 90 degrees.
which passes the capture attribute as "coord"
and sends it to the material.
