Convert 3d file into cmod with texture
Convert 3d file into cmod with texture
Hi Everyone:
I found this nice vesta 3ds model but I´m afraid I cannot load texture when running into Celestia;
https://nasa3d.arc.nasa.gov/detail/asteroid-vesta
Can everyone convert it to cmod or make this 3ds able to load texture and not only the naked 3D model?
Thanks a lot!

Few minutes ago I made a cmod binary model and add texture

Thank a lot! and new line code to add color and ambient light
Thank you very much for you answer!
The model looks fine! However I would like to ask you if the mesh model you use to create this cmod file is the same as I suggested, because that 3d model is full of details!
Regarding the other user, it is true that there is a bit of "double Effect".
I would like to suggest this line that includes color for the asteroid and lunar lambert for a more realistic general light feeling (rewrite the following code at inside "asteroids.ssc" file in "Data" folder and it could be fixed this double effect we won´t be more happy!

Yes, this is model from your suggestion https://nasa3d.arc.nasa.gov/detail/asteroid-vesta

Alejandro, it's best not to modify SSC files in the data folder unless you know what you're doing. It can sometimes cause objects to not appear. You should take the code posted above and make it it's own SSC file. Use this code below, paste it into Notepad or equivalent, and name it vesta.ssc and place it in your extras folder.
Code: Select all
Replace "4 Vesta:Vesta" "Sol"
{
Class "asteroid"
Mesh "vesta_big2.cmod"
Texture "vesta.jpg"

If you see that I made a dumb or nonsensical post years ago, please forgive me in advance.

your texture is interresting, the East-West orientation corresponds to what we see on the IAU website, my old texture was upside down. But the ssc file is a problem. When displaying the locations on the asteroid (coordinates from the IAU) there is a shift of about 20 ° to the west. Should not we correct the MeshCenter or Orientation ?

What to change in the ssc file:
After modification
Added after 1 hour 47 minutes:
the original texture vesta-topo.dds (Art Blos) does not match the orientation of your vesta8k.jpg
As an attachment, the corresponding texture (Nasa) : 11521x5761 pixel
(dimensions can be reduced if necessary)
Code: Select all
Orientation [ 30 0 1 0 ]
#MeshCenter [ 0.77 3.424 -0.554 ]

it's the same alignment as the 8k texture of vesta_big
If you use the vesta_big texture, the vesta-topo.dds texture will not be aligned in the same way.
In addition the mesh should be oriented 30 ° on the y-axis as I said before, so the surface locations will be in the good place.
Added after 7 minutes 21 seconds:
vesta8k (normal), this is the texture of the addon of limax7 viewtopic.php?p=140710#p140710
vesta-topo8k is the texture AltSurface "topography" which corresponds to it

Ups, my mistake. Long=0 is in the center. Sorry
