It's very incorrectly packaged. Please fix that.
After checking out, there are several errors in the config-files of those models.
For example:
md3alphatest Mesh 0
mdlalphatest 0.7
The
md3alphatest
command will be overridden because
mdlalphatest
is also being executed.
The shader which you've used it just the "caustics"-shader. It has been officially used in the assassin and ctf-edition of Sauerbraten on several hudguns.
Only the model which is in the "1d" folder, uses a different shader. But too bad it doesn't seems to be working correctly.
