How do I make a nebula's parent body set as a star eg: Betelgeuse? +would the string "Dist" effect it?

Source of the post Since i am new to the site and can't create my own thread i am going to ask here (thread hijack...sorry) Are there more detailed instructions on how to import models into SE? I am super interested in learning, however following the instructions I found on this site for importing .obj files...I haven't had any success. Ships always appear....well they don't appear at all when I build them in SE. I have tried with a few 3ds models i found on the web. I have converted/exported them to .obj files in 3ds max, but they all turn out the same. Any suggestions or tips?


The directions should be fairly easy to follow, it would be hard to figure out your issue without more information on what you are doing with the ship files.

Did you follow these directions specifically?

One reason for your problem might be that you use incorrect folder names.
For example 'addons\models\spacecrafts' or 'addons\textures\spacecrafts' instead of 'addons\models\spacecraft' and 'addons\textures\spacecraft'.  Without 's' in the end!
(In earlier versions of SpaceEngine it was 'spacecrafts').

Okay so I want to make a system based off of this.

How would I create those other barycenters with those red dwarfs and have correct orbits?

Sorry that is has been a few days.  I appreciate the responses.
  I did check my directories and it is "spacecraft" instead of "spacecrafts".  I spent some time and re-did everything again following the directions on this site step by step.  When I build the ship in SE, i still have the same issue.  However, i checked the SE log file and see the following:
[00] Loading  model "#/models/spacecraft/addons/Star Trek/USS Perdriau.obj"
[00] ERROR: seMesh::LoadOBJ(): Error opening the file "#/models/spacecraft/addons/Star Trek/USS Perdriau.obj"
[00] No new materials, materials library has not been created
Any ideas what could be causing this?  There is a mtl file in the textures directory that was generated by 3ds.  The mtl file seems pretty empty so maybe that is the problem?
Anyway here is a link to the files in one drive if anyone wants to take a look.  The model is one I found on the internet so I take zero credit for its awesomeness or unworthiness.

The system already exists in SpaceEngine.
Actually, you only need to make a script for the planets. Add the planets to 'ParentBody "MU Her Aa"'.
But it will not work quite well, because in the original system the orbital times do not match with the 'SemiMajorAxis'. The semimajor axes are too short.
I've changed this.
Also, I added the star 'Mu Her D'. But it is not clear whether the star actually belongs to the system.

Help with creating Mods and Addons

Cpt.Picard, nothing I can do with that model besides standard detail diffmap.  Your obj file has no data for an MTL file and your MTL file is blank.

You need to export it again and preserve the texture information, or provide a link to where you got the model and I can look into it for you.

I got the model from www.trekmeshes.ch.  Thank again for the assistance.  I am sure it is something i have done or not done that is causing the problem, but I am a noob trying to learn.

I was wondering if there is an easier way to make planets and stars? I'm don't know coding that much. 

Help appreciated.

Cpt.Picard, I will give it a go but I always have issues porting those models.  Klud has a way to do it that I haven't quite figured out yet, I will still look into it.




I did get the model exported and semi working, I am not sure how it will look in engine and it may require the use of detail diffmaps for some of the hull plating. I will work on it and update you with some screenshots soon, if it comes out properly.

Here is a very simple 'tutorial': A very simple tutorial on how to create a solar system.
I think it goes not easier.

Be careful with that site. The author of that site is a known copyright infringer who has been banned from the Celestia community, iirc. At one point, the original copyright holders had to sign up to the Celestia forum and post in order to expose the infringers.


Edit: Anyways, a few questions of my own. Firstly, I am considering releasing a music mod, similar to Pluton's, but my own choices in addition to some of his choices. My choices include several songs from a few Nintendo games. However, since Nintendo has been extremely aggressive as of late in cracking down on shared files, is it worth the risk? Or might it be safe to post my music mod here?

My other question, my latest changes to my TPE universe has the Sol System undergoing several stages of change, using several different files named by year, like so:

Image

Basically, to see earlier time periods, one simply moves the latest year file to a temp location. To see later time periods, just simply re-add the later files. However, I do not know how user-friendly this is, or if I can make this more user friendly. Since the preferred format of addons is pak files, would I need to use multiple pak files for each Sol Sys time period? How do I make this whole thing user-friendly?

Plutonian...Thanks for the info.  I will be careful.  I am just really trying to learn at this point.  I have no intention of infringing, stealing, etc. Just playing at this point.

I made two galaxies mod but they don't work. Yes i've followed the instructions in the manual as to the placement in the addons folder but i suspect it's a problem with the scripts i've made. If anyone can enlighten me I would appreciate it.

You have wrong quotes - instead of ".

This means you have: 'Galaxy EGS-zs8-1 and 'Type Sb ' instead of 'Galaxy "EGS-zs8-1" and 'Type "Sb".
This is because you copied the script from the manual. There are wrong quotes.
