A question. When defining a cascade controller, is it important that the early stages of the controller go before the later stages in the config file?
Yes, this is the optimal arrangement.
> Alternatively, do the individual PID controllers get processed in
the order they appear in the config file each frame ...
Yes.
... or are any dependencies worked out behind the scenes?
No, the pid evaluator just runs each pid module in the order they are specified in the config file.
If order is important, I assume that you could get a 1 frame lag between each PID stage if they are in the wrong order.
Yes, that is what would happen.
