Could someone create an .stc that updates Antares to have the new artistic texture as well as Antares' blue star companion?

I already have the texture file:

Please take the information needed from https://www.aavso.org/vsots_alphasco

(note: do NOT include the nebula as I have another addon that includes it. I will upload the finished file to Celestia Motherlode.)

Thank you, Joey p.

The stc is quite simple:


See the addon that I've included below.

Unfortunately, though, there are some problems with the surface texture image: it should be a power of two on a side and twice as wide as it is tall (e.g. 2048x1024 instead of 2000x964) and it needs to be an "equirectangular" projection. As it is now, it results in a "polar pinch" of the star's surface. See below.

Doesn't matter; thank you.

When I tried to replace the existing texture with the new one, it would not work. Do you know how to fix it?

Make sure you're using the correct file name: either rename the jpg or edit your .STC file.

Except for that minor glitch it worked fine for me.

Still doesn't work, there might be a bug, but I think it could be OK.

Anyway, where is the type B companion? There is no addon in the motherlode that includes it.

Here's a crude addon. I had problems finding good values for orbital parameters.

Thanks. - Joey P.

what minor glitch for "antares1.png"

it is a normal everyday sRGB png image

The minor glitch was in the .stc, not in your image, which is fine.

The texture specified in the Antares .stc was "antares.*" so in the updated antares.zip Addon, I renamed your image to match.
