Hi Mark!

I thought that there were only two options for the axes (Z or Y upwards), but I found a few options of importation in RF.

YXZ (LW, c4d…), ZXY (3DSMax, Maya…) and YZX (xsi, Maya, Houdini…) and it is this last preset which it should be used when one imports a still .obj in RF…

To import an animation in RF, it is necessary to export from Carrara in .MDD (LW), load it in c4d to transform it into .sd file for RF. The Fenric's MDD plugin has an option to reverse the axes. Now, that work for me...

Thank you for your research on this subject and also for the explanations in the vertex modeler !

Cheers!
