Hi Martin, >From what you've written it's difficult to know exactly what you've done wrong or are mis-understand. A complete c++ example would be easier to know exactly what you've done and to recreate the problem.
The role of the outputParameters in the ScriptEngine::run(.., Parameters& outputParameters); method is to serve as a list of parameters that the script itself populates. The way you use it is to pass in an empty Parameters vector, this then will have zero of more osg::Object's assigned to on completion of the run(..) call. Does this help? Robert.
