OpenBeta 1.0.4 and TileLayers?

Hi,

So Tile Layers have changed a bit in 1.0.4. I've managed to deal with all the changes, But my tiles won't render. They cause collisions, but they dont render. If I create a static sprite using the material they are using the sprite renders.

Can anyone think of what I'm missing?

T2DTileLayer baseLayer = new T2DTileLayer();

            baseLayer.Name = "floorTiles";
            baseLayer.Layer = 1;
            baseLayer.MapSize = new Vector2(550, 550);
            baseLayer.Size = baseLayer.MapSize * 3;
            baseLayer.TileSize = new Vector2(3, 3);
            baseLayer.Position = new Vector2(0, 0);
            baseLayer.VisibilityLevel = 1;
            baseLayer.Visible = true;
            baseLayer.SortPoint = new Vector2(0, 0);
            baseLayer.CollisionsEnabled = true;
            String defs = "";
            baseLayer.TileDefinitions = defs;

            T2DTileType tile1 = new T2DTileType();
            tile1.Material = (DefaultEffect)TorqueObjectDatabase.Instance.FindObject("GGLogoMaterial");
            tile1.Name = "tile0";
            tile1.CollisionsEnabled = false;

            baseLayer.TileTypes.Add(tile1);
            baseLayer.DefaultTileType = tile1;

            TorqueObjectDatabase.Instance.Register(baseLayer);
