MESH_POINTS with Geometry Shader

[SpiderPig]

I've had no luck with this.  When I add a geometry stage to the material family, it's fragment shader no longer works.  The points seem to be showing the background color.   I've got a simplified example here, it should move the verts a bit and they should be green.

#include "UltraEngine.h"
#include "ComponentSystem.h"
using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1440, 900, displays[0]);
    auto framebuffer = CreateFramebuffer(window);
    auto world = CreateWorld();

    auto camera = CreateCamera(world);
    camera->Move(0, 2, 0);
    camera->SetClearColor(1, 0, 0);

    auto light = CreateDirectionalLight(world);
    light->SetColor(5.0f);
    light->SetRotation(35, 35, 35);

    auto floor = CreateBox(world, 100.0f, 0.5f, 100.0f);


    auto model = CreateModel(world);
    auto mesh = model->AddMesh(MESH_POINTS);

    for (int z = 0; z < 100; z++) {
        for (int x = 0; x < 100; x++) {
            mesh->AddVertex((float)x / 10.0f - 5.0f, 1.0f, (float)z / 10.0f);
        }
    }

    model->UpdateBounds();
    model->SetMaterial(LoadMaterial("Materials\\Point.mat"));


    while (window->KeyHit(KEY_ESCAPE) == false && window->Closed() == false)
    {
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

Question: Do you have a matching depth pass shader you are using for the depth pre-pass? You can disable camera depth pre-pass to test this.

Ah yes that is the problem.  Where does that go in the shader family JSON?

{
	"shaderFamily":
	{

I have found it.
