I've noticed that "Package for Renderfarm" is only working once per session on a particular project.
For example, while working on a project (under pressure for time), I saved a view, saved the project, Packaged for renderfarm, got the "select Package for renderfarm folder", did that, named it and all worked as expected. Then I sent it to a renderfarm, so everything worked...happy.
Then, I need to make a few changes to the model, saved a new view, then go to Package for renderfarm, and nothing.
The only way I can get it to package out is to restart FormZ, then it works again (but only once in the work session).
