I'm currently writting a pluging for output PointCache2 file,I met a problem,How can I get the event of smoother modifier applyed to a figure have done it's work?
thanks!

During the export process, calls to DzObject::update and DzObject::finalize will apply the smoothing operation synchronously.

Or you can use the builder classes. They do the update and finalize for you. Something like this:

 DzObject *obj = node->getObject();
 if ( obj )
 {
  DzVertexMeshPtr geom;
  DzNoFilterBuildGeometryFilter filter;
  obj->buildFilteredGeometry(node, & filter , true , geom );

  if ( DzFacetMesh *facetMesh = qobject_cast(geom ) )
  {
   // do something with mesh.
  }
 }

Thank you for you replay,But I got same problem,I just don't understand how the buildFilteredGeometry class works,I noticed that somooth modifier do the job at a asynchronously process,so I guess i have to wait the signal when it finished work before I can do something,I just don't know how to get that signal,thanks again!
