Perhaps make the atompshere of the planet on the tome bigger (its in the internal network)

Will

Yes Will, I think that may help here a little to make it further off the surface.

dhavalmistry, also be aware that you have the sun very close to the horizon of the first planet and thus you have a different angle that the sun is hitting the second.

You may also want to compare your other atmospheric settings on both planets.

also he could add anouther sun the near the horizion of the top planet but not make the disk visable.

I am sorry I didnt quiet understand what you are trying to say but I tried raising Haze and bluesky height and it didnt quiet make any difference

I am uploading a copy of my tgd file for you guys to look at

Changing the angular diameter to zero and disabling the disc visibility for the sun will not work.  No light will emanate from the sun.
Any, even a very small setting of angular diameter will result in an appearance of the second sun due to the glow....unless you turn haze and bluesky glow amounts to zero.

I don't understand what your saying, You don't need to see the sun to get like to emante from it.
also Im looking into the .tgd

@Will...try setting your sun angular diameter to zero and uncheck disc visibility....you will see what happens...
Title: Re: Need some help with Atmosphere settings
Post by: Will on January 23, 2007, 03:46:14 PM
well im suggesting (and currently testing) that you just uncheck the visable box but leave the disk visablity intact. But ill try it and see what happens. Im not questioning you just trying to help dhavalmistry.

Will

I think people here are missing the obvious. The second planet has no atmosphere. Since the object resulting from "add object->planet " doesn't have an atmosphere input node, just copy/paste the existing planet, move it into position, copy/paste the existing atmosphere shader to get a new one and connect that one upto the new planet.

3Dguy it does but he disconnected it in the internal network. Ive connected it and trying again.

ok so this is what i've come up with, I tryed using my idea with the other sun and it seemed to work but you can see a small disk though the amosphere, Also I couldn't get the halo around the planet but you could try making the ceiling larger.

Will

@Will...I guess you confirmed what I said before...
"Any, even a very small setting of angular diameter will result in an appearance of the second sun due to the glow"

Title: Re: Need some help with Atmosphere settings

yea like you said but I guess you could get rid of it in photoshop if we can't come up with anouther way to help him.

Will

thanx guys...you ppl are really helpful...

so this thing cant be done without the second sun?
Title: Re: Need some help with Atmosphere settings
Post by: 3DGuy on January 23, 2007, 05:42:01 PM
The difference between the bottom and the top planet is that you're just in the atmosphere of the bottom planet and hence the atmospheric glow is very visible. The top planet doesn't have less glow, it' just far away and you're not in the atmosphere itself. I think this is the problem you're facing. It's probably unrealistic to expect the top planet to glow as much as the bottom one with the current view.

Or I'm understanding this all wrong :P

yea I know thats why I said he could make the ceiling a lot heigher but you guys can feel free to play with it ;)

I did it the way I described earlier and raised the atmosphere ALOT and ended up with this.
Haze exp height 40000
Bluesky  exp height 80000

Disabled some stuff to speed up the render, like the clouds.

Nice going 3DGuy...now can you help me out with what changes you made to the scene so that I can achieve similar effect too (i.e. if willing to)  ;)

Thanx

Basically, select your second planet "yellow", goto the internal network and reconnect the atmosphere to the cloudlayer's input. Doubleclick the atmosphere node (of the yellow planet) and then set the haze exp to 40000 and bluesky exp to 80000. Also the haze density was turned down to 0 like in your main planet.

What I did in this picture was just clone the main planet and moved it to where your planet was (copied the coordinates, and size). Then copy/pasted the atmosphere of planet 1 and connected it to the planetcopy and made the above adjustments. Don't forget to remove or disable your yellow planet if following the last option :P

Thanx 3DGUY....Its been great help from you and all others.

I've uploaded the final version of the render with some tweaks...I hope you like it
