[Feature Request] Forward Scattering in translucent materials

Hello, I'm currently working on a cloud system which uses translucent particles/billboards.
Unfortunately there's no option to change the way light scatters within a material.
For clouds/fog it's essential to have forward scattering enabled.

My current workaround is to use a special shader that manipulates the material thickness depending on the view direction and light positions. Ofc I need to pass all relevant light directions/positions to the shader to make it work, which is a kind of tedious process.

So it would great to have that feature out of the box, either by a per material setting or per diffusion profile.
