Adding Textures to My Models

So that my models look more realistic, Ive decided to add metal shaders to my models so that they look more like metal space crafts rather than having a matt finish. To create the shader I go into the Materials editor and I then select one of empty spheres and then change the parameteres. First I change the type of shader it is from Blinn to Metal;

Now I can change the Ambient colour of the shader;

And the Diffuse Colour;

Then finally set the Specular Levels and the Glossiness;

Now I have my texture ready for the models;
