Thanks! That was indeed the issue. So I assume the GDP is empty when the cook starts?

Hi, I'm having a small problem trying to process multiple groups. I've created some groups both with my own code and with the standard group node, but my second node is not picking them up. I'm sure the created groups are primgroups. This is my code inside of the cook method:


//Try 1
GA_PrimitiveGroup *grp;
GA_FOR_ALL_PRIMGROUPS(gdp, grp)
{
int i = 0; //Breakpoint here
}

//Try 2
GA_PrimitiveGroup *polyMeshGroup = gdp->findPrimitiveGroup(“polymesh”);

if (polyMeshGroup == NULL)
{
addError(SOP_MESSAGE, “No polymesh groups found to build structures.”);
return error();
}


Is there something else I need to process before I can access the groups inside the detail?

Although it is deprecated, you can unhide the DOP's with the opunhide command: http://www.sidefx.com/docs/houdini12.5/commands/opunhide [sidefx.com]
