Hi,
I am wondering how to mix two attributes with VEX. See attached a screen capture when I try to mix color attributes.
for some reason I can't get the value of the second wrangle input.
vector vA = v@opinput1_Cd ;
vector vB = v@opinput2_Cd ;
@vA = vA ;
@vB = vB ;
@Cd = (vA +vB )/2 ;

input numbering starts form 0:
vector vA = v@opinput0_Cd ; // or just v@Cd
vector vB = v@opinput1_Cd ;
@Cd = ( vA + vB )/2 ;
you can also use lerp() to blend them in any ratio:
v@Cd = lerp (v@Cd , v@opinput1_Cd , 0.5 );
