some question about how to use texture and light in blender ?

Hi, I am new in CS and Blender.
Over the last days, I followed the "Portal tutorial" to creat a portal in CS. And when i ran the model I see nothing in the window. Then i created a lot of lamps in the model. But i still see nothing. I don't know why! Is lamp are also handled in different way in blender than in crystalspace?! And another problem is that in "General Overview" and "Overlay Interface", it said "Materials are handled in a very different way in blender than in crystalspace. Because of this, a special material tab exists in blender2crystal to set crystalspace related material properties." But in the documents they gave little information about how to use "material tab".
Can you tell me where i can get more information about how to use lights and material in blender2crystal?
