Here is a shot about the lighting question.


The blocks on the right have no shader. The top two blocks, it is hard to see the bump map working as the bump map matches the texture, however the lower two show the bump clearer.

There is a dynamic light model that is emmiting a blueish light, which can be seen on both the non-shader versions on the right, where as the left pair only seem to be illuminated based on the suns location, which is set to 0,0,0 in this example. The light follows the cameras location and angles.

I will take a look at some of the other shader threads here and see what I can learn. I posted these shots for reference.
