I will be able to post some zipped files of various OA planets soon on Alan Kaslev's OA site; I have upgraded most of them so they look better, with specular reflections and so on...
however I am hitting a problem making .stc files for the more distant systems
this is my stc file at the moment;
Oshiq is supposed to be in Perseus, Guanche is supposed to be in Cygnus;
802801 "JD 9802-8"
{
RA 3.53206 # Star for system containing Oshiq
Dec 51.2142
Distance 3210
SpectralType "G2V"
AbsMag 4.3
}
802802 "JD 76601"
{
RA 19.88206 # Star for system containing Guanche
Dec 43.5641
Distance 2899
SpectralType "G2V"
AbsMag 4.1
}
-----------
but they aren't showing up in the right places
where am I going wrong? is the celestia coordinate system different somehow? Sorry to be so dense...
Nearly ready

Hey Steve...
Definitely looking forward to those files! Will they be all that you have done to date?
I'm slowly working on a texture for the first world in my setting, Ghellhonus. Hopefully, I can have it done in about a month (I have very little open time during the summer, ironically).

I don?t find anything to download,suitable to Celestia.Only an OA page and utilities

No; they are not ready yet; I want to make suitable stars for the more distant worlds; thanks to Grant I can do that now.
The textures are not really hi-res, it has to be said; I don't have the graphics tools for that. But we have tried to make the worlds reasonably realistic.
John; I would certainly like to see Ghellhonus and other Arcbuilder worlds in Celestia; don't forget to annonce when it/they are ready.

By the way; this is an Orion's arm wormhole; held open by a geometric framework of negative matter, this is an entirely artificial construct, and if you entered this hole you would travel no more than a planck length before you reached your destinaton- perhaps less exciting than a Farscape or Star trek wormhole, but it does the job...
NICE. I've always wanted to see a good visualization of a wormhole. Well, an artificial one, anyway. Question, though: wouldn't you be able to see the "otherside" through the face of the wormhole, as if you were looking through a window? Or is that just a soft sci fi falicy?
Also, is each face of the wormhole a different destination?
Anyway, the Ghellhonus texture is just a very simple exercise in cloning from various other sources, and certainly can't hold a candle to most things that I've seen here. However, if you want, I can email you the texture (no cloud or bump maps; those are a bit beyond my knowledge base at the moment).

I've amended the wormhole so you can "see" the stars on the other side; they are supposed to be visible, although distorted.
Each wormhole has only one destination- it is a spherical volume which connects two different three-dimensional volumes of space,
just as two flat sheets are connected by a circular wormhole in the diagramattic representation we are all familiar with

Let's see if this image appears-
so the hole in the wormhole should be a spheroid if it connects two volumes rather than two flat planes- (I think)
the purple struts in the image I posted earlier are just there to keep it open. You dont want to collide with them though, as it would make the whole hole collapse.

To make them function in Celestia it would take a script that said something like goto (cel/url) in zero seconds;
this is something that should be doable...
as far as real life ones go, it might just be possible to pass tiny amounts of information through them one day...
but spaceships?
even though I write about them all the time, I don't think they will ever be big enough for that.

Maybe not naturally, but through creative use of anti-matter structures, I can see it. The question is, how to organize anti-matter in a universe of matter. I know we can produce the molecules, but for how long until they explode? How can we create a structure based on anti-matter?
Oh yeah, and what would flooding a wormhole with anti-matter particles do?

Well, the matter that holds the mouths of such and artificial wormhole apart is actually negative matter, not antimatter; this is an entirely theoretical type of matter with negative mass and inertia.
It wouldn't explode on contact with normal matter like antimatter does; but it certainly would have some strange properties.
If it existed.

I personally am more enthusiastic about the concept of negative energy in the form of negative cosmic string; this is preferred by Visser in his more recent forays into the theory, I believe.
