Sun for a Planet

Ok… I recently made a planet, and I want to make a sun for the Background, and I’ve been experimenting with halos, but it ALLLLLLLLways looks way too small… not so much sunish as distant starish… the center of the halo is only like a pinprick, but I want it to be HUGE compared to what it is now…

what it looks like now… also, is there a way to get it to show up through the kind of force fieldy thing? it looks really bad with it not showing at all :S Thanks all!

(ALSO: CnC is welcome and desired for the planet itself…)

I’m not sure what you mean by force field thingy, but to increase the size turn down the hardness and turn up the HaloSize value.

I mean the blue/red bubbly thing around the planet… I want the halo and the stars to show through it a little…

I worked on it a little more and solved the size issure… so far I am up to this now…

I still have the issue that I said up there ^^^^ though

nebody? %|

I found something else I don’t like… is there a better way to make clouds around the planet? these ones look really crappy…

that tut has very little to do with any of my problems… thanks for not reading my posts…

Actually if you looked at the tutorial it has very detailed settings for the clouds. They may not be what you want or require but the guy was just trying to help – lighten up.

halosize: Turn hardness down. If the edges of the sun are too blurry for you, use a texture to make them sharper.

clouds: Look at that tutorial that was given to you for the clouds. It’ll help a lot. In fact, that’s the best planet tutorial on the net for blender in my opinion. (And a lot of other people’s from what I’ve seen on these boards.)

force field thingy: Turn down alpha, and in the raytransparancy options, press ztransp (if you want your sun to be distorted by the field, you’re shot, unless you want to replace your halo with an alpha mapped plane, but it won’t look great.) It should show through.

I Have a way of making clouds, but, its complicated and eats up rendertime:

If you have ever read the tut for “fur” back in the day, then this would be easier to explain. Try making a sphere that has many layers, something akin to, say, a baseball, just with alot more layers (at least 9) with very little space in between. Now, give it a texture (try cloud for starters) and make sure it starts at alpha 0 (from the left hand side) and goes to alpha 1 (or less, if desired). Now, make your sphere material ztrans, and all shadow options turned off to see where the general layout is. Change your ramp sliders to where you wish, or the noise size/depth, or even the mapping size. When that look suits you, turn on all shadowing options (even bias if you are using ray) and voila:

Notes: Won’t work right with reflections or refractions, and shadows may look…odd at certain points.

Now, the sun part is easier - layer halo points:

I did this with 4 points, 1 with your general halo with hardness all the way up, alpha 0.5, add 1.0; another with your general halo, hardness all the way up, alpha 1.0, add 1.0, and about half the size of the first; another with the star option, hardness all the way up, alpha 1.0, add 1.0, and a little bit bigger than the second point but smaller than the first; and lastly was a halo with the lines option enabled, hardness all the way up, etc., and about the same size as your “star” halo.

Notes: Pretty much the same as above.

Hope this helps :slight_smile:

The best way to do clouds:

Create a second sphere. Just duplicate the one you have and increase its size by hitting ‘s’ then 1.010.

Find or create a nice cloud texture. Now I use the Flaming Pear plug-in for photoshop to this, but search around NASA’s website as well.

Go back to your original sphere and create now a third, this one sized to 1.020. Clear all the textures and make it’s colour some shade of blue.

Now, go to the shader tab and click raytransparent and set the fresnel level to 2 and fractical to whatever you want. This actuall takes a little playing around with.

Finally position your lamp where the sun should show through to the camera and render. You should get that light shining through effect. (make sure you have raytracing on)
