Yes, I do think adding support for newer model types would be good. Perhaps
even add support for models done in solid works....

Using the example program as a reference I was able to successfully
render one of its included md2 models. If anyone needs a very spartan
starter tutorial, my basic code looks like this:
' Model array declared at beginning of Render module.
Public Model[32768] As Md2Object
' Model loading procedure test (index 500 is arbitrary).
Dim TempModel As Md2Model
TempModel = Md2Model.Load(BasePath & "/model/test/md2test.md2")
TempModel.Texture = LoadTexture(BasePath & "/model/test/md2test.jpg")
Model[500] = New Md2Object(TempModel)
' Render command after OpenGL matrix has been set.
Model[500].Draw
I've been having a hell of a time finding decent modeling software that
can export to the md2 format, as it is very old (though quite nice for
my needs). I created an untextured cube in Misfit Model 3D (1.3.7, stock
Kubuntu 13.10 repo) and exported it to md2, but my code raises sig 11
when it tries to execute the Draw method.
Does anyone have any insight into what modeling applications exist that
can export to md2 format? I'd love to learn Blender, but all the md2
export scripts I found failed. I think they were designed for older
versions. Maybe I should look for an old Blender version...or contact
the Nexuiz team. Any advice is appreciated, and to whoever wrote the sge
component, thank you.

Maybe the best will be to add another format more accurate with the current
technologies.
Thanks everyone. I'll give the mentioned programs a try and keep
investigating.
I looked up Blender's stock export formats on Wikipedia and the only one
that looks useful is X3D:
http://en.wikipedia.org/wiki/X3D
http://www.web3d.org/realtime-3d/x3d/what-x3d
Seems geared toward rendering in a web browser, although I don't know
why it couldn't be implemented outside of one. I searched the package
names for x3d and couldn't find anything. Maybe there's a lib out there
somewhere.
I finally got one of the md2 export scripts for Blender (2.66.1) working
(attached). I modified the Md2Model example project to use my exported
test md2 as a replacement for its "bauul.md2" data file so you could see
it crash. I'm guessing it is because the test md2 has no textures, so
I'll try that next. The modified project is here:
http://eightvirtues.com/sanctimonia/misc/Md2Model.tar.gz
It crashes when the Draw method is executed.
