Even though they are largely composed of water ice, comet nuclei aren’t translucent in any of the NASA or ESA images I’ve seen. However, only a handful of comet nuclei have ever been imaged at close range so who knows?
The brighter reddish patches on the “darkside” of my object are meant to be “active” regions on the surface. Today I added a gas jet that erupts from one of those red areas. In reality, the night-side of a real cometary nucleus would probably be as black as coal, but I have to “hollywood-ize” my stuff to keep it lively (thereby keeping my clients happy).
You are right about Smokers; they are very useful. There are eleven in my project so far, and I expect that number to increase.
See you later,
