in general the loader sets the name on everything it can.
However, MaterialChunks are Attachments and those can not have
attachments themselves. Therefore the VRML loader can not add a name
attachment to the MaterialChunk.
If you are in control of the VRML files you load (and therefore know
their contents), you might get around this by looking for the
Appearance's name instead.
Hope it helps,
