Fog and skybox fading?
 

Hello.

I want to make a "cloudlayer" simulated by an area of white fog at the bottom of the map with the skybox around it.
And I'd like for the lower parts of the skybox to fade into white so that the fog makes sense and actually works.

Got everything set up, but not sure what kind of shader I will need for the skybox, if that's all?

Thanks for the help.

I'd imagine all you need to do is paint the bottom of your skybox the color of the fog, and then do a gradient on the 4 side images so that it smoothly transitions from your sky to the color of your fog. I don't think you need to alter the shader at all. Just a regular skybox shader will do.

Gradient as a png from sky to transparent, or sky to color? Because I think the latter won't give the fog effect due to the sky shader being what it is. But I know it's been done before, just can't remember who or what ..

That tutorial isnt for fogs but uses the technique you want for a part of it. Scroll down to the bit labelled 'Photoshop Only' - thats the bit that deals with painting your skybox the same colour as your fog.

There's also some maps with source files you can check out (READ: BlueIce Nightfall) which use fog and skybox editing.

Basically SartStevenus is right, you just paint a gradiant along your 4 side images and a solid color on your _dn image (all matching your fogparms rgb values) and write a shader to use the new sky images.
