Fog effects layer?

[skinnytorus]

Hi, guys.
Are there any plans to implement fog effect as a special layer? For now, a combo of the depth mask and a constant layer seems to do the trick, but a proper fog layer wouldn't hurt. Another thing is the ground fog effect. There's no substitute for it now. Any workaround possible? Then... planetary atmosphere effect? No easy solution again (using a volumetric light might be too heavy in terms of performance). Perhaps these can be among possible options for the fog layer. What do you think?

Not a bad feature request I must admit. Bringing an eaiser / faster access to the feature is always nice for users.
But then since that's already things you can do with masks (for the depth fog) or vertex masks (for the ground fog), I don't think it will be a priority just yet !

or vertex masks (for the ground fog)

Vertex masks for the ground fog? Interesting. How do you do that? Could you upload an example file?

OK. I think I figured how to make ground fog.

Here is what I did:
1. Changed the color of the main compo background
2. Added alpha component to the material layer with a 3d linear mask
3. Added mask to the sky layer with a 2d linear mask.

Is this the right workflow? Is there an easier solution?

Thanks in advance.

Nicely done !
You could just mask the Diffuse directly I believe, but that doesn't make it that much faster. It is indeed the way to do it. You could also put your linear mask in a function to remap it onto something like a sine, making it a little smoother!
