New track won't load [solved]

[thelusiv]

I created a simple track using Bob's Track Builder and Blender:


It has about 6 turns and some ridiculous camber on some of the turns. I am using this as a test for working with BTB, which I am going to be doing some more work with once things are working smoothly.

Here's my track: http://vdrift.while-true.net/closed_track_1.tar.bz2
The above tarball contains all the following:

• DirectX (text) format .x files exported from BTB
  
• .blend file created from importing .x files in Blender and manipulating somewhat
  
• VDrift track folder for closed_track_1
  
  • objects exported with export-all-joe-0.3.py, jpk created using joepack utility
    
  • list.txt created by the above Python script
    
  • roads.trk created with vdrift-trackeditor
    
  • track.txt created with vdrift-trackeditor
    
  • about.txt

The problem seems to be that it's not loading the surfaces. The symptom is that it fails

Code:

assert (surface_id < (int)surfaces.size());

in src/objectloader.cpp:275 (I modified it slightly to split up the assertion conditions and printed out the variables, which you can see in the output):

Code:

So, any ideas what could cause the surface loading to fail, so that the surfaces vector ends up empty? Whatever is going on, vdrift-trackeditor didn't choke on the track at all...

One other thing, BTB seems to like to use 5 vertices across the width of a track, but vdrift-trackeditor only supports 4...I just used 2 for this export. Could this be causing the problems I'm having?
