? Mars&Venus addons appear at the wrong point in their o

[Liar]

Hey all,

I have recently downloaded Globemaker's beautiful Mars and Venus models, named:

Mars model 1x
Venus model 1x

I put them into Celestia following the readme.txt file that comes with the Mars model - i.e. creating an "Addons" folder within:

celestia/extras

...and then just dropping an (unzipped) copy of the whole directory into that folder, so that it looks like this:

celestia/extras/Addons/venus_1x_cmod
celestia/extras/Addons/mars_1x_cmod

Celestia will display both models, but they both appear at different points in Mars and Venus's respective orbits to the Mars and Venus globes already in Celestia!

i.e. i now have two Marses, and two Venuses: they appear as four seperate planets, in four seperate places: Mars, Venus, another planet called Mars_x1, and a planet called Venus_x1.

Does anyone now how to put my new Mars and Venus models in sync with the proper positions of Mars and Venus in their orbits?

If i do get them into sync, will i be able to be sure that Celestia is placing Mars and Venus in their correct positions, or will they take on the new positions of the two "new planets"?

thanks for any feedback.

You need to modify the .SSC catalog files that came with the models. To place them exactly where Celestia places the real planets, insert the lines

Code: Select all

CustomOrbit "vsop87-mars"

and

Code: Select all

CustomOrbit "vsop87-venus"

in their respective files. These will override whatever Orbit definitions are there now.

Alternatively, you can tell Celestia to use these models instead of its default spheroids. Create an SSC catalog in the Addons directories which contain these lines:

Code: Select all

Modify "Venus" "Sol" {Mesh "mesh-name.3ds"}

Code: Select all

Modify "Mars" "Sol" {Mesh "mesh-name.3ds"}


replacing "mesh-name" by the appropriate name.

You can disable the existing Addon SSC catalog(s) by changing their filetypes to ".sscNO" or you can delete them.
