I want to believe this is a frequent or an easy question but I can't find anything.
Can I add new types/classes of objects? I'm making a map of my and my friend's fictional objects, and quite a few stars have a non-existent spectral class, hence it can't be recreated with SE's usual system.

Refer to the manual

The manual does not contain yet references to wormholes.

I would like to know if it is possible to create wormhole, and if yes, how we can create them ?

A simple pair of linked wormholes can be created with this script placed in SpaceEngine addons\catalogs\planets\ folder:

Star "Wormhole 2"
{
   ParentBody "Sol"
   ConnectTo "WormHole 1"
   TunnelLength 2
   Class "Z"
   
   Orbit
   {
   RefPlane "Equator"
   SemiMajorAxis 1.4
   Eccentricity 0.01
   Inclination    2
   }
}

Star "WormHole 1"
{
   ParentBody "Sargas"
   ConnectTo "Wormhole 2"
   Class "Z"
   
   Orbit
   {
   RefPlane "Equator"
   SemiMajorAxis 1.4
   Eccentricity 0.01
   Inclination    2
   }
}

G'day Folks

I have had success creating wormholes in our local planetary system but I cannot seem to create them to jump Interstellar or intergalactic.

When I set the parent body and load space engine the exit wormhole at the other end so to speak is not there.
Forgive for seeming dumb on this, I cannot seem to get enough info out of the Website manual to explain these things more clearly.

Also can I set something a little better than the semi major axis of the object so its easier to put closer to a destination planet.
I can't see or understand how I can maybe set the radius of the object from the parent body or something like that.

Thanks in advance folks, not sure where to sift this info if its exists already.

Cheers

Can't say much without looking at the actual script, but in general pay attention to the syntax or missing quotes. The se.log file in your spaceengine system folder probably has some clues about what's happening, search for "error" or "warning" lines.
As a general rule, ParentBody objects must be catalog objects so you can't use procedural objects like "RS 0-1-0-114-1828-4-2338-900 7" or "Benetnasch 4".

oh, It's not yet in the manual, but you can use
SemiMajorAxisKm
to express the orbital distance in kilometers.


You have definitely answered my question if I cannot use procedural objects which is a shame.
Can you catalog objects out there to allow wormholes to exist in distant places?

Or can I go out and reference an area where I can simply place a wormhole anywhere in the procedural universe to connect to.

"Going to need some serious exotic matter to light these wormholes up"

Thanks Mosfet I appreciate the response.

Good fun tinkering with space engine.
