[SetMaterial with Manually Created Models/Surfaces]

I am working my way through some of the sample code and making slight modifications. I am stuck with a very simple problem. I cannot manage to get a model to successfully render a texture.

 

I am using slightly modified code from the leadwerks docs and a stock material.

 

Any insight to my challenged code/thought process is appreciated.

 

#include "App.h"

using namespace Leadwerks;

App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}

App::~App() { delete world; delete window; }

bool App::Start()
{
window = Window::Create();
context = Context::Create(window);
world = World::Create();
camera = Camera::Create();
camera->SetRotation(5, 0, 0);
camera->Move(0, 0, -6);
Light* light = DirectionalLight::Create();
light->SetRotation(35, 35, 0);

Model* model = NULL;

model = Model::Create();
model->SetColor(1.0, 0.0, 1.0);
model->SetPosition(0, 0, 0);

material = Material::Load("Materials/Concrete/concrete_dirty.mat");


Surface* surface = model->AddSurface();
surface->AddVertex(-0.5, -0.5, 0, 0, 0, -1);
surface->AddVertex(0.5, -0.5, 0, 0, 0, -1);
surface->AddVertex(0.5, 0.5, 0, 0, 0, -1);
surface->AddVertex(-0.5, 0.5, 0, 0, 0, -1);
surface->AddTriangle(2, 1, 0);
surface->AddTriangle(0, 3, 2);
surface->UpdateAABB();

model->SetMaterial(material,1);
model->UpdateAABB(Entity::LocalAABB | Entity::GlobalAABB);

return true;
}

bool App::Loop()
{
if (window->Closed() || window->KeyDown(Key::Escape)) return false;

Time::Update();
world->Update();
world->Render();
context->Sync();

return true;
}
