preamble:

I tried to send this patch also to the mailing list away-dev at google groups but the group doesnt accept emails from the public.
Please open the group so people without google accounts can contribute too.
Not everybody wants to share his cell phone number with google

Hello everyone,

Cinema4d’s collada exporter may produce files where node tags include subnodes and instance geometry.
Something like this:

<visual_scene>
<node>
<instance_geometry>
          ..
</instance_geometry>
<node>
          ...
</node>
</node>
</visual_scene>

I’m not into collada that much so i don’t know if this is part of the spec but i’d like to share a patch which also handles this setup.
First look at source it seems these changes can also be easily applied to the away3dlite and 2.5.x versions. I can provide patches therefore too if you like.

kind regards
Martin
