Hi guys,

I just discovered three.js about a week ago and whoa... what a great great toolset!
I´ve been dreaming about something like this for a long time, the possibilities are just... well, whoa again :-) Congrats, excellent job!

Well, since I downloaded the latest version I´ve been playing around with the possibilities, including the awesome collada import. Now I stumbled about a really strange problem, I hope you have a hint for me in which direction I could investigate:

All the available example files of the collada loader work fine for me (monster/koi-skin/demom). But when I try to use my own files ( biped animations, skinned, created in 3ds Max 2010), nothing is displayed at all. Not even the stats or the grid will show up, just blackness. (well, yes, the paths are set correctly..)

Simple scenes with basic geometry and without animation exported as dae - no problem. But as soon as I attach a modifier like skin or physique to the model and export it via OpenCollada: nothing - no matter what parameters I use for the export. Though I saw that e.g. 6ert´s koi-file was exported via OpenCollada as well... hm.

I don´t think that this is a Max/OpenCollade-issue, my files can be re-imported as dae into max, and they work - just like e.g the monster.dae, which I can load into max and watch it crawling around in my viewport. So the file structure of my dae´s seems to be basically ok....

So my first question is: is anybody out there who succesfully exported a collada file out of 3ds Max with animation and material and used it with the collada loader? I opended the working example files in an editor and compared them to mine, and at first glance they seem to have the same structure...

Any idea what I am doing wrong or where I overlooked something?
I hope this question is not too stupid - I´m more a graphics designer than a code genius... Basically, it seems like the collada loader requires some special specifications of the dae file that my files don´t meet. Could you tell me which specs these are?
