How to access a detail attribute from a COPs Snippet VOP?

[Nicholas Ralabate 19]

This is probably a simple question, but I cannot figure out how to grab a array detail attribute from /obj in my COP Snippet.  I am trying to render an image where each pixel contains part of my detail attrib array, as follows:

 

int test_array[] = detail("op:/obj/oinkster", "test_array");

R = G = B = test_array[1];

 

This is all inside of a VOP COP2 Generator... Where am I going wrong?

try to provide path to a geometry node (SOP) not just object

like this:

"op:/obj/oinkster/OUT"

You don't need the op: prefix. That is only required if the parameter expects to a filename.
