Looking for an atmospheric shader I found some nice shaders, but the main problem is that the actually shaders creates a “halo” making this effect looks great from space, but the problem comes when I land into the planet.
So I’m looking for a way to make a “3D” atmosphere, or a fade with the planet color (sky) to the space or vice versa.
Maybe you’ve seen this effects in some games, like Spore.
Nothing?
Maybe I can do it with the particle system.
But it’s too “ugly”.
try the “crease” image effect with a negative intensity and a bigger radius. maybe that’s what you were looking for?
I’m using free Unity, that’s the big problem 
I’m looking a way to do it, I know that I/we can! ^.^
Check the part when the spacecraft go into the planet, is awesome

Yah, I know, with a free version I can’t do something like this, but I just want one thing.
Note the atmosphere, there is a “halo” as an atmosphere, and the ambient light, the sky, changes when you go into.
I have sun, random planets, and clouds, but I haven’t this effect =(
You can defiantly do that with the free version of Unity. It’s just a shader on a sphere. It’s actually a well documented effect, covered in Nvidia GPU Gems 2 which you can view for free on Nvidia’s website, a lot of other articles online have covered it as well. You’ll want to be on the ball with shader programming to get that happening in Unity though.
The biggest drawback to this effect is that in the GPU Gems 2 article the shaders depend on a fixed ratio between planet size to atmosphere size, so unless you’re building nothing but earth planet clones it’s too inflexible for most game purposes set in non-earth fantasy systems/galaxies.
I did it!
But… well, its too weak.
No special shaders, just and inverted sphere with a transparent shader.
I know thats not the correct way, but still works :razz:
I keep in working to make this effect better.
It’s me, again!
Finally, I use an inverted sphere (flip normals), and the X-Ray shader, here is the result in a empty planet.
If anyone is interested, tell me and I’ll post the unitypackage and a explanation, but I did it by the easy easy way.
Looks very cool but… still it isn’t what I’m looking for!
Anyway, thanks for your help guys, but, any ideas how can I improve this?
I have still one problem, when I look upper the space invade the skies. There is a “faded hole” in the sky.
Edit.: Problem solved
i think that the under water look ‘plugged in’ when atmospheric shader’s are enabled. Like they have full bright and a truckload of glow or something. Disabling Atmospheric shader’s reduces the effect to an extent, but when traveling over water, those plants (and nothing else) appear to be at the surface. And a bit too bright.so that it also effect on the earth atmosphere size because it depend on the planet size.
Hi! It has been a long time since your post, but I’m looking for something like that. Do you still have the unitypackage? 
I’m looking for the same package or a easy way to do it.
