Hello rashad546

Unfortunately, the feature you’re asking for is not possible because the plug-in was not designed to work that way.  Here’s why;

First, the plug-in isi designed to export whatever material is attached to the objects.  The plug-in doesn’t know which material is “default”.  That means, that if the plug-in sees a material called Lambert1 attached the pSphere1, it thinks the user has created a lambert and called it Lambert1. Also, it would be dangerous if the plug-in would start deciding on it’s own whether or not to export a material.  What happens if the user decided to name a material Lambert1 on purpose?  Or wants to export Lambert1 with very specific parameters?

Second, the FBX plug-in doesn’t know that you are exporting to Max.  The way it works is that, Maya takes the information you have, puts it into a package which the plug-in takes and creates an FBX file with.  After this, it’s Max that reaches out and grabs this FBX file and brings it into Max. It’s not the FBX file that decides to open itself into Max.  It’s possible to take that FBX file and open it up in Soft, or MotionBuilder.

I am not sure if it will help, but you can try and disconnecting the default Lambert in Maya and then exporting the objects with no material.

Hope this helps,
Regards,
Carlos
