I am modeling earth and have managed to come up with a fairly good base. I am having trouble with maping the clouds and was wondering if anyone could help me out with a few other bits if pos too.
The problem with the clouds is that i cant seem to get the transparency right, the pics below show how the earth is looking at the mo with no clouds so you can see how it should look and how it looks with the cloud texture (if you cant see the image for whatever reason, there is little / no transparency where there are no clouds). I have tried a few things in the hypershade with alpha etc. which i could go in to but was just wondering what the correct method was.
Also if anyone could offer any advice on how i can make the atmosphere not visable on the dark side of the planet. I already have a facing ratio node pluged in to the transparency so i cant plug another node (surface luminance?) in to there also.
Also, what would get the best results for the dark side of the planet in terms of city lights? Would you advise to use the surface luminance node and shining a light on the dark side of the earth to do a seperate render to then composite in after effects? :edit: Iv just been trying to connect the surface luminance node to my earth texture, out value to transparencey. It doesnt seem to be working, am i doing it right and is there something im missing?
Any thing you can help with would be great.
Thanks so much, apologies for the long post
Good news, iv managed to sort the clouds out! Here is how its looking so far:
Im still struggling with how to get rid of the atmosphere on the night side though, the problem with pluging a luminance node in to the transparencey is that i already have a facing ratio node pluged in there. Anyone have any suggestions?? :-/ Is it possible to plug two different utilities in to the same input? Are there any work arounds except for the pikey seperate render and masking out in AE solution?
Thanks for any help
