Hi!
I want to write a collada exporter and I’ve run into problems. My exported file couldn’t be loaded. I tried the viewer app shipped with collada dom and with GLC-player. viewer crashed, while GLC-player says ‘file is corrupted’ at opening. I tried the coherencytest application and it can’t find any problem.
Do you suggest any other tools that can tell me where is the problem with that file?
The generated collada file from my program (for a simple cube):
<?xml version="1.0" ?>

I tried this without any effects and materials, still doesn’t work.
Thanks for any help.
