I have a Color Ramp node that I'd like to go vertically up a default cube. The cube hasn't been rotated, just raised on Z to a value of 1. Why is the ramp placement not defaulting to either a vertical or horizontal alignment? I could play with the rotation settings on the Mapping node, but even then it's not a perfect 45 or 90 degree setting.

    $\begingroup$ It's because you connected a vector (dark blue) socket to a float (gray) socket, which averages the XYZ components I think. Put a Separete XYZ node in between and feed its Z output into the Color Ramp. $\endgroup$

  • $\begingroup$ That works! If you post as an answer I'd be happy to give it to you. Also, any idea how to make the gradient span out farther? It's a fairly abrupt transition, I'd like it to be smoother. $\endgroup$

    $\begingroup$ @Increality for that, I would say a gradient node would be better, you can map it more easily also and can also change the type. $\endgroup$ Commented Jun 7, 2022 at 5:55
