Hi Greg, thank you very much for the reply and the lovely feedback.

Yes, XPresso can sometimes expose a lot of parameters. Perhaps that helps:

Drag the Object into the XPresso Editor.
With the Object active, drag the parameters from the Attribute Manager to the blue square of the Node, and let go of the "mouse". The wanted Parameter should be established as input. If you need an output, drag the Parameter from the Attribute Manager on the red square of the Node.

Example use: Output can be helpful to explore how a Pulldown menu was coded. Like in the Random Effector, you have more options. See image. This helps to know about "hidden" parameters.

Each of the entries is coded with an Integer number. So you can change the entry via XPresso.

Thanks for the feedback file. Yes, that looks stable. If there was a question and I missed it, let me know.

As a side note, the Take System might be a great addition to the sequencing of image output.

Enjoy your project
