Returning a string/Array of Strings in CVEX (Material Style Sheets)

[Nandu]

Hi,
 

This is Nandan from SPin Vfx.
 

I am working on Material Style sheets in Houdini 16.5.
 

I want to add add subdivision groups under Render Polygon as Subdivision (Mantra) on the rendering geo.
 

I see I can create a Render Property override on the geo in the style sheet and set it to one.

To specify the groups for subdivision (which is also a render property on the geo) I wanted to write an inline script in cvex to return an array of string to fill the subdivision parameter.
 

My question is:
 

1) Can that be possible? Can I return a string from cvex and populate the subdivision group parm on the geo using style sheets. I do not want to hard code it, I want to return it from cvex

2) Should I be returning an Array of Strings from the cvex funtion, if there is more than a single group.

3) Can I get any reference to working example?
 

Any help will be much appreciated.
