Hey guys am done screaming about this, it will be done when done.
Its just sad that a “next gen” engine is missing something so important, and it makes me sort of frustraited.
BUT there are some small things we can do. 
On the UE 4 Roadmap
As i understand it they first need to complete, Parallel rendering implementation
And then they can get bussy on Forward shading support (translucency, more shading models).
I posted a qustion about Forward shading support (translucency, more shading models) for todays stream lets hope they answer it.
But for now everyone vote, i think thats the best way we let Epic know how bad we need this.
Edit: No plans for Forward shading support (translucency, more shading models).
as of yet.
We just have to wait guys
