GA_FOR_ALL_PRIMGROUPS not picking up my groups

[WesleyE]

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?

No, if findPrimitiveGroup() can't find your group then it's not there.

I've posted this on the sidefx forums as well. I misunderstood what the gdp contained at the beginning of the cook. The gdp holds the previous cook, not the first input, so I had to do a duplicateSource to get it to register.
