I believe the skyx material files we get are all in the media/skyx folder. The SkyX_Moon.png in there is mainly used for the background so it's probably not going to be useful as a texture for the moon surface.
It would be cool to make the gazebo background black or use a texture with stars.
Yeah, is it possible to change background color/texture in gazebo? I think normal ODE has such interface...
The background color can be specified for world files, but not for model files. Maybe we can change the texture with skyx?
try adding this somewhere inside the <world> element of your world file
I approved this, and will fix my two comments once merged in.
Note: Merging this won't make it appear in the model database, so we have a bit of flexibility. We'll update the model database once the associated gazebo pull request is merged, and the two comments in this PR are resolved.
Do we need one sdf file for SDFormat v1.4 and a different file for SDFormat v1.5? It seems that the files are equal.
They are the same. There is no harm in keeping both, that way someone with an older version of sdformat can still use the model.
I was thinking on using the file with version 1.4 for people with older versions but not a big deal.
Ahh, right. We could do that. I'll put that on the list of changes to make.
