can you share one of the models that cause this problem? There is
perhaps some (implicit) assumption in the code that your models happen
not satisfy, but without an example this is difficult to debug.
As far as I remember the VRML loader tends to produce multi indexed
geometries and there might be a subtle bug in how they are handled. A
possible workaround could be to call createSingleIndex() to remove the
multi indexing.
Cheers,
Carsten
