Hello guys,

need help with a conditional inside switch node.

I have a wall , sometimes with odd number of prims (3,5,7..) and other times pairs numbers (2,4,6..).

Depending that number the switcher must select the correct one (0 or 1).

I need the wall divisions to be CENTERED in the wall. With de RESAMPLE node it seems imposible.

¿¿What is the correct code to apply??
should something like this:
if(nprims('../reverse5')==0, 0, 1)

Thanks in advance.

You can use a bbox expression and a spare parameter in the Divide SOP's Size parameter to center the divisions.

Ok. Thanks.
Thats one part of the problem.
But I need the use of SWITCHER between odds and pairs.
... Or use VEX > Wrangle(primitives) to switch pair/odds from input.

Years ago I saw that code, now I lost it.

In documentation there is only a mention to ot in Arrays
int odd = nums; // { 1, 3, 5 }

Sounds like you want
nprims('../reverse5')%2

You may need to swap your inputs as even numbers will return 0 and odd ones 1
