I have not enough time to convert track I've made , I'm making character animation which wi'll be ready in few weeks.
So it would be great if someone exporting tracks I've made.
You can find sources on http://stkaddons.tuxfamily.org/ , Log yourself and download blender files .
It's easy to do :
1 convert textures in .png
2 In blender , in UV textures windows , select a texture then click on replace
3 find the texture folder , and change texture
4 Repeat for each .png (You can see that blender give you a link to the selected folder
5 Save and export but I don't know how , I've never use the new script yet
I'll send you all my congratulation by advance
