I have the impression that here there are more Paraview users than on StackOverflow. I already posted a few questions there, should I migrate them? Or cross post?
It is never a good idea to cross-post questions on the stack exchange. We highly discourage it. If you haven't received a suitable answer on stack overflow, you might be able to get an answer here. No guarantees, but it's worth a shot. My recommendation is to delete your old post on SO, and repost it here.
