Error exporting mesh

[fabioped]

I'm trying to export a mesh file (CMF) from one of the Complete Characters MAX source file (female). At the second step (bone assignment) I can't get passed this, receiving a message error: Invalida material, please set a material on the node.

Here's a screenshot of what I'm getting: https://dl.dropbox.com/u/178438/cal3d_error.png

My objective is to save every morph from the face expression and use it in vizard as possible face morphs.
