Hey !
Im new to houdini and I'm learning by some tutorials
in a part of it i need to give thickness to the spoon and i should do it with points node - color gradient ( … –> point –> VOP SOP –> attribpromote –> Polyextrude –> … )
But the gradient is not in the right direction
as you can see its on X axis - left to right

but it needs to be like this on the Z axis - up to down

and sorry if its so simple but i couldn't find out how to do it !

the gradient is along x axis since you are using $BBX which at your first 2 images is across the spoon
so just change your expression to $BBZ or 1-$BBZ to get gradient in Z axis

in your 3rd image X is actually along the spoon so in there $BBX would work
