I’m just reading the tutorial by Colin and I think it is great, but right now I’m stuck in the middle of part 2.
I don’t get along with the colorband settings: http://wiki.blender.org/index.php/BSoD/Introduction_to_Materials/exercise_2#EXERCISE
Why are the first three colors defined although they have an alpha value of 0? The colors are not visible at all! So why do I have to set them? I hope somebody of you read this tutorial… I tried to contact Colin but I can’t find an email address.
