We'll look into developing a corresponding shader to it, once the figure is fully released.
The current release (demo) version doesn't reflect the quality of the final product, so we'll look into it, once it's actually out
I'm gonna guess no. Project E, while she was cool, didn't really take off with vendors. I love the work Ero did on her, but she just didn't catch the eye of most. Now, La Femme on the other hand....she is looking MUCH more promising for adoption.
I can definitely say, that we probably won't be supporting Project E anytime soon.
LIke Nephanor already mentioned - she just ended up becoming too much of a niche-product (very unfortunately).
