Hi everyone,

so i want to create a vector attribute that has xyz where xz are static floats and y is the actual y position.

I would have thought putting it as such :

v@centerpos = (0, @P.y, 0)

but when I do so all it does is full the xyz with the z value in the geometry spreadsheet and I cant figure out why NOR how to solve it... anyone can tell me what I'm missing ?

ie : if i put (0, @P.y, 1) i get : 1 everywhere and if i put (0.0.@P.y) i get P.y on all three fields (xyz).

Hi Fellow houdini users !


I'm really just beginning my exploration of this magnificent software and am encountering 2 problems in my current project :

1 - using a color Sop im choosing Ramp from attribute and I can't get it to ramp the color based on the point numbers ? It seems so intuitive and logic but there's probably a catch because it doesn't work when I put Ptnum or P or N, in the attribute field ? Is there a resource as to what are the valid values for the attribute field ?

2 - Is there a way to - lets say I have a nice variety of colors in the range of the rainbow to reduce the number of colors (as the quantize would do in Substance Designer) so that I end up with 7 colors for example instead of all the subtle variation ?

thanks for your support and cues to improve my understanding !
