I wrote a function which creates corresponding obj.cfg files for exported models generated by the writeobj(...) function. Located in worldio.cpp. If you implement such a function I would turn to Sauer-enhanced. Below is the example code and the documentation. You have to paste it into worldio.cpp file of Sauerbraten:
<code>
/*
Write a Cube 2 level as model file and create a matching texture config.
usage: writemodel [name] [scale 0/1.0] [noclip 0] [ambiente 0/100%] [specscale 0/1.0] [info]
This command writes Cube 2-map geometry as textured wavefront obj file to packages/model/[name] folder.
Multiple subdires are allowed and - if required - created. Shaderparameters are translated as good as possible.
Alpha-blending is only supported for images with alpha channel. Dont use the alpha-material,
just apply an alpha-texture as normal stdworld texture or with spec/bump/env/glow parameters. The created model will turn it on.
Alpha-materials and sky-surfaces are removed. Use a plain, white diffuse-map with envworld shader turned on to get a skybox-effect then.
Also mdlenvmap command with the required skybox has to be added manually to the object config. See mdlenvmap of the model-doc.
Supported shaders: *specworld, *envworld, specmap or glowmap, envmap, bump*, alpha-channel
Shaderparams (monochrome only): envscale, specscale, glowcolor
Parameters:
name: model name, located in the packages/models folder.
scale: size of the model, default is 1.0 (400%).
noclip: create a clip-box by default (0) or disable clipping, if specified (1).
ambient: see mdlambient command, zero means default value (100%) or -1 turns ambient off.
specscale: specularity scale of the model, see mdlspec in the models-doc: zero means default (100%, 1.5?) or -1 turns specularity off entirely.
This value is usefull to adjust specularity of textures, for example phillipk textures require a higher value (3.0)
while mitaman's meters are looking better with values <1.0
info: write shader info, in case manual adjustment of the output file is required
Example script commands:
mapmodelreset;writemodel test;mmodel test;newent mapmodel 0;
Those commands called in editing mode writes the curent level as model test and loads it as model number 0.
Note: the mapmodel list is also cleared and an instance of the model is being created - near the curent selection.
Bugs:
* parallax is not working and if glow-map is specified, the specularity is disabled because masks have to contain
spec- and glowmap which mismatches then. Also texscroll, alpha-material and pulseglow are ignored.
* Sometimes the glow is too dark, when glow is enabled and the underlaying diffusetexture has dark pixels at this position.
* Glow, spec and envmap-colors are interpreted as monochrome values.
* When plain envworld shaders is specified, the reflection of the model is not plain, because the chrome-map has to be enabled.
Use a plain diffuse-map with envworld shader to get mirror, or skybox-effects then.
* The texturedata of your model must have the same packadir as your model when using two or more subfolders.
Sauerbraten would requires a objdir command or similar to fix this issue.
* The *.mtl file can be removed, its not required.
* When stencil-buffer is disabled, alpha-blending cuts off models behind an alpha surface (this is a cube-specific blendfunc bug)
Tested with textures of aard(default), philipk(glow, spec), lunaran, mitaman(spec) and painkillah(envmap) and some envworld/specworld shaders.

PS: I made a mappack containing top-rated quadropolis maps, mostly not in svn. It consists of maps with at least 8.5/10 points and more than 15 votes. If you want to include those in Sauer-enhanced, just tell me, and I will upload it. There are lots of textures and Mapmodels in it. By the way, nice work with your map spaceshift, I love the texture which change its color when looking to one of the flags.
