Hey,

simple one hopefully.

How can I make my Cd greyscale in vex?

@Cd = relbbox(0, @P.y); Returns a color value.

Just want to remap those values to greayscale, something like hsvtorgb?

Thanks!

Just assign the same value to all three RGB parts.

v@Cd = set(@P.y,@P.y,@P.y);

@Cd = luminance(relbbox(0, @P.y));

Or you can just do:

@Cd = relbbox(0, @P).y;
