    Question about COLLADA plugin for Maya

    The following is a mail conversation I had with Christian (working on the importer/exporter for Collada in Maya)
    ... that I thought I should post here since it can be very helpful for others.


    Thank you for your interest. I suggest that you post this on the
    public Collada forum, since it would be of interest to others too.

    I'm only testing on Maya 6.0.1 and 6.5. If you have 6.0, I strongly
    recommend you upgrade to 6.0.1, it's a free upgrade anyway.

    Not implemented yet, but it's in the plan.

    No one else has reported that problem. There's probably something strange
    happening with your plug-in path. Check your Maya.env, verify that there is
    no duplicate of COLLADA.mll left around. I'm sorry, but I just don't have
    the time to provide end-user support on this plug-in.

    Yes, this was an actual bug. Thanks for reporting it. It will be fixed in
    the next release.

    Good luck on your side. If you still can't get the plug-in to load properly
    in the Maya UI, I would suggest posting on the public Collada forum. Maybe
    others have had a similar problem and will have the time to help you. Sorry
    I can't be more helpful,

    If you still have the script problem after you've updated to 6.0.1, please read the following:

    There was a problem with the installation batch file. Basically, the mel scripts need to be copied in the scripts/others folder, not "scripts/unsupported". You can get the latest plug-in from sourceforge, it should have the fix.

    Some people also reported that doing a "rehash" in the script editor helped.

    If more people get this problem, let me know.
