Far Galaxies and New Stars

[InconspicuousBarrel]

I am developing two addons which will add stars and planets and galaxies not listed in Celestia or on the Motherlode.

New Stars: http://www.zshare.net/download/776409827b5dc9bb/

Far Galaxies: http://www.zshare.net/download/77700251e3c058ae/

Bugs/Glitches: The model for Hoag's Object (Nebula) will not show a texture and the CustomTemplate for Hoag's Object (Galaxy) does not work.

Feedback and help are very much appreciated.

Okay, in that case, what would you recommend?

Okay thanks. I'm going to update the links in a minute.

With a quick look at your Hoag 3ds model, I found several problems.

1. The texture image is not a power of two on a side. This is required by most 3D graphics hardware.

Fix: either scale it to be 1024x1024 pixels or cut out a part of the image, creating a new image file that's 1024 pixels on a side.

2. the material is dim.

Fix: In your 3D modeling program, create a new material that is white and has a diffuse value of 1.0. Then associate the rescaled image file with that new material.

3. The texture is not projected onto the visible part of the model. It seems to be projected onto the (squashed) side of the sphere. It needs to be projected onto the top of the sphere.

Fix: enable UV mapping while viewing the top of the object. Adjust the image so it looks right in the modeling program.


Then:
Export the model as a new 3DS model
edit your DSC catalog to refer to that 3ds model
view in Celestia.

translate the 3DS model into CMOD
edit your DSC catalog to refer to that CMOD model
view in Celestia.

Thanks, I was wondering why none of my 3D models showed texture.

Also, I'm working on a new version which has more galaxies, corrected axes and angles and corrected Right Ascension.

NOTE: I will post the new version tomorrow. It includes many billboards.

Here's the new version with quite a few working billboards: http://www.zshare.net/download/77700251e3c058ae/
