Thanks, i tried but it doesn't work without connecting it to the camera (something that I don't want to do), and the way my scene is set, there is a total dark area behind Earth so that type of shader won't work. I'd need something that glows but also shows transparency from where the camera views. The kind of Earth atmosphere I'd like to make is like this:Here is a tutorial for planet making. It shows how to make the atmosfere glow.
For space clouds use any technique to make clouds or dust and just put it in space.

Here's what I'd want to use for a comet. They are nParticles. These I'll have to figure out a way to attach them to the comet body and have them emit as the comet moves.To freeze the particles you can disconect them of the emiter in the dinamic relationships window or delete the emiter.
If you have crashing problems you should try sprites, they are very light to render.
edit:
Wow, this asteroid goes directly to my head
Thanks, now I just have to figure out how to do that parenting to polygon.Just parent the emiter to the comet geometry.
To stop the nparticles choose an initial state when they look fine for you and delete the nucleus or uncheck enable..
To stop particles do the same and check off is dynamic in the general control atributes.
I would lower the specular color of the planet and tweak the specular parameters because it looks almost metalic unless you want it like this. It could be earth before the oxygen produced by algaes oxidized the iron disolved in the sea making it bue.
Hmm, I've totally neglected the outliner all this time, had no idea what it was useful for. Thanks.to parent, only drag and drop whith the middle mouse button in the outliner.
It's not like i was planning not to use it. Just never knew what it was for. O.o That sounds horrible lol...then you can use edit/parent.
If you are planning not to use the outliner you will most probably develop serious mental damage.
when using the nparticles is better to uncheck colisions and self colide if you are not using it.It will make the whole thing faster.
Thanks, that worked, but for some reason, the cloud just won't appear in the scene. Even if the cloud is in front of the camera, it just won't be illuminated. It has a Particle Cloud texture assigned.Select the nparticle object and go to nsolver/initial state/set from current.
Then go to the nucleus (in the atribute editor) and uncheck enable.
The nparticles will keep the same state you chose in set from current.
to export, select the nparticle object and go to file/export selection.
It shows in the list.ckeck that is lighted in window/relationship editor/light linking/light centric.
Maya hardware dont render particle clouds.
Also the particles could be in a layer that is deactivated.
Also check what camera are you rendering, could be another one.
