so you are writing your own filegenerator, right?

If I am correct, then the contact between box and sphere is ignored
unless you write this line inside filegenerator in function
createActors :

interactionGeometryDispatcher->add("InteractingSphere","InteractingBox","InteractingBox2InteractingSphere4SpheresContactGeometry");


I think that the Funnel FileGenerator example does what you want: it
is a collision between spheres and boxes.
