How can I make a translucent material that also has an opacity fade?

Think…Milky Way!!

Like at night in the sky…
i have a simple plane style model one-sided with some curves and what not to replicate what It’s look like in the sky at night.

For the material so far I have a perlin noise green channel lerped with a couple scalars to make the opacity look a little foggy which it good. and a little emissive and frennel work for a finishing touch.

The only problem I have are the rough edges of the mesh…I was wanting to know if there is anything I can do with the material that would make the sides of the mesh kind of fade…so they aren’t such rough transitions with my skysphere…once again…I’m making a milky way…literally/.

So simply, how can I have the material set the sided of my mesh fade to translucent??

thanks guys :slight_smile: Hope I worded that OK.

Can anyone tell me if what I’m trying to achieve is possible?

Hey AttemptD -

I believe this is the setup you want to use. I have subtracted to Fresnel effects with different powers to allow the removal of the edge but keep the central opacity as well.

Thanks Eric, that works amazingly. It’s a perfect solution for planetary scale atmosphere. Could’ve just wasted a year trying to perfect Rayleigh scattering.
