I'm getting an error loading a collada file that only occured after
adding animation information from 3ds Max. With a static model and
textures, the file loads fine. I suspect either the OpenCollada plugin
is somehow messing up on the export, or the Collada parser is not
familiar with one of the animatino elements.
I'm working to get the model running exported animations and any help
getting past this sticking point is welcome :).
Thanks,
Sean

Gets the error in the parseNode function while processing the
"instance_geometry" node case. The line that breaks is:
(_objectData as MeshData).geometry =
geometryLibrary.addGeometry(g...@id, geo);
--------------------
The node in the collada file that is breaking starts like this:
<library_geometries>
<geometry id="geom-P_CTRL_FootR" name="P_CTRL_FootR">
<spline closed="1">
<source id="geom-P_CTRL_FootR-positions">
<float_array id="geom-P_CTRL_FootR-positions-array"
count="12">7.36045e-6 4.70477e-7 -11.99407 7.34664e-6 9.484941
-1.99891e-6 7.2269e-6 1.57992e-6 22.1596 7.3717e-6 -9.48494
-3.93307e-6</float_array>
<technique_common>
<accessor source="#geom-P_CTRL_FootR-positions-array"
count="4" stride="3">
<param name="X" type="float"/>
<param name="Y" type="float"/>
<param name="Z" type="float"/>
</accessor>
</technique_common>
</source>
There are a couple of things I noticed in trying to determine whats
broken. 1) This file introduced the <spline> node which was not in the
exports I have used without rigging and animation data. 2) according
to the Collada spec, the closed attribute in <spline> is a bool, and
defaults to false. Perhaps there is an issue with true being
represented as 1 from the exporter (I did try changing the value to
true and got the same error)
