Why am I HERE?
I want to ask very much specific question about a problem I faced while making a realistic earth model in Cinema 4D. There are dozens of tutorials available on this topic in youtube and other sites. But all of them neither satisfied me nor solved my problem. I think you guys can help me.
What is the problem?
In the real images of earth taken from the space, the edge of the earth appears to be very much diffused and one cannot find any sharp boundary (may be it depends upon exposure of the camera). See the image below.
Now in all the tutorials (I have seen) they failed to make such a diffused edge having no boundary between earth's land and the atmospheric glow. So ,how their earth looks like, is the following:
Next I tried hard to make the edge diffused but I failed and this is my problem. So, where I have ended is as following:
What do I want?
I want somebody to help me to make the edge diffused as real. Please tell me how to do that?
Note: I have used three materials as texture for earth, cloud and atmosphere on three different sphere of increasing radius. Then "object glow", "glow" and "color correction" is also used. Any other technique will also be appreciated. More, my version of Cinema 4D is R 16 studio.
Caution: I have asked this question before to some other people. They have suggested me to use photo-shop to make the diffusion. But I am creating a 3D model and wish to animate it. Therefore, photoshopping will not help me!
