[Papervision3D] COLLADA Max NextGen - animation problems

[Paul Tondeur]

Hi Tim,

Thanks for your reply! I've just tried to remove the parent animation  
elements, however the COLLADA doesn't seem to be nested and this did  
not solve my problem. I had second look at a DAE that is working. The  
structure seems the same, I don't see any more nested elements  
compared to the other. A difference between the two is that COLLADA  
Max gives each animation node an ID attribute, where COLLADA Max  
NextGen doens't export it with an ID as attribute. I've manually added  
an id attribute, which seems to solve the problem for me:

   <library_animations>
     <animation id="one">

I've also had a quick look on how this could be solved by the  
papervision code, but I haven't nailed it down yet. Maybe this gives  
you a clue where to solve this? Or is it a specification of the  
COLLADA file that animations need to have an id attribute? In that  
case the people at Feeling Software should try to fix this in their  
next release.
