Could be worth a try, yeah.
You’re right, that’s what bothering me as well.
At the moment it’s a simple ramp material and i set the x size value to the max on the input. I need to find a better solution for this.
Since i’ve never done such things on blender i’ll need some tests but i’ll figure it out 
narf. I am frustrated about the material, light and rendering settings so far (a little bit). The material for the strings and the light would not work out just like i want it to… and even the low setting calculation takes much too long °-° sigh ah and btw, i just hadnt much time in the past few days to work on this again…
