Custom export generic model transform issues

[Anonymous]

Hi,

I am currently working on a custom exporter to export multiple views to collada files. I used this tutorial, to handle node transformation : http://thebuildingcoder.typepad.com/blog/2013/07/adn-mesh-data-custom-exporter-to-json.html

But still, it seems that some given transform are not correct (I am probably missing something). I have this view :
 
and my export is currently giving me this :

 As you can see, one in two element has an inverse axis rotation. And my debugger certify this statement :

the grey block "node.GetTransform()" is the previous instance node iteration, and the white one, is the current one. Do you have any idea why the basisX and basisY axis are different? Am I missing something?

Thank you.

I've explored this further, and I saw that one of two is the mirror of the first one, as you can see in the image bellow. Why isn't the transform giving me this mirroring transformation?
