Topic: Spacescape(Space Skybox & Skydome) Example

This is an example of a Spacescape(Space Skybox) that I have been working on today using gimp, this is entirely (Automatically Generated) the Texturemap is 8186x6142 so its high resolution(no blurring or pixelation). This is only the "Starfield and Interstellar Gas" portions I still have todo ...

1. Star Field (Done)
2. Clusters
3. Nebula
4. Star
5. Interstellar Gas (Done)
6. Vortex
7. Galaxy
8. Lens Flare

Anyways tell me what you think so far.

Re: Spacescape(Space Skybox & Skydome) Example

Starting to get the hang of it.


I think I am going to have to make the planets in gimp and use them as billboards, if I cant figure out a way to create atmosphere.

This one is a Skydome, getting the seams to blend is turning out to be a pain.

Looks pretty good. Is that planet a part of the background or a physical object?

Its a physical object, I just wanted to see how it would look..

A sphere a bit bigger than the planet with same origin of the planet, standing still while the planet slowly rotates, with alpha value so you can see the planet terrain through its clouds.

Thanks 225, that actually gives me an idea, what you said but with an animated texture, for clouds and lighting storms etc.

Here is what the spacescape(skydom) above looks like from outside. This thing is so big, that from the outerwall that planet is not even a dot, and the planet is 10x the size of blenders grid plane.

Re: Spacescape(Space Skybox & Skydome) Example

This is for those that don't know how to use this.

The Galaxy is simply your scene/level, all objects in the galaxy are placed in any location in the scene. Typically you would place a blackhole in the center but you don't have to you can use a Sun or any object. We will use a sun in this example.

1. All objects in the solar system are parented to the sun unless they are parented to another object (example: Moon Parented to Planet).

2. As the sun rotates all objects in the solar system will rotate with it, all objects parented to anything other than the sun will rotate around there parent.

3. All child objects can have there own rotation.

4. The  Skydome is a visual representation of your galaxy, and it "Follows" your camera, so your camera can rotate freely but when it moves on its X,Y,Z axis the Skydome moves with it. We do this because the Skydom can only be so big and we dont want to endup on the outside of your skydome.

5. As our camera moves threw space, distant objects will slowly come into view.

If only we had a particle system.

We do have this, its not ideal but it does work ...

I prepared a new example to show how to do particles using lua (in progress) :
http://www.maratis3d.org/download/SpecialEffects.zip
In this first example, particles are created using a quad made in blender with an additive blend mode.
The life of the particle is controlled by a material animation changing the diffuse from white to black (in additive black is transparent), so in lua we can control the life duration by changing the animation speed.

Re: Spacescape(Space Skybox & Skydome) Example

I forgot all about that. There was a post that fixed it (It was broken before, kept crashing Maratis, I need to look back at that again now that I am a little better at Lua and Maratis) Thanks.

No problem I will do a tutorial on these Spacescapes later so you guys can make your own, there easy to make for the most part, making them look uniformed and hiding seams is a little tricky.


For those of you looking to make some extra cash, these can sell for about $5.00+ each if there nice.

Re: Spacescape(Space Skybox & Skydome) Example

I think I posted on here some time ago, a link to a tutorial called "Woodland..." something. He used Blender to create a scene of the woods. In that tutorial he showed how to get rid of seams. I found it if you wanna check it out. It is pretty long though:

Thanks but my seams are from me getting to close to the edge of my uv bounds with my gimp nebula brushes. I just have to be more careful. But with these set your material to black with no specularity, your skybox/skydoms black background will blend with your material.

This is not how it works IRL. Every planet has its own orbit. You should find some equations online and simulate an elliptical orbit.

I know, in real life everything orbits the barycenter including the sun. I am not that good with math, trying to implement some formula will only server to frustrate me and failure.
