Guess I never thought of that. That would probably end up making it very
similar in performance to a group, but I'd have to do some performance
checks to be sure. . . Maybe I will later tonight :)

Well, the short answer is, exactly how you are now. Other than drilling
down into a model Resource, and shader, you can treat a group EXACTLY like
another model. It still has a transform, a world transform, can have
parents, children, etc. In terms of positioning elements in the world, it
behaves no differently.

As I implied above, in this part of the code you shouldn't need to change a
single line. You can treat the group exactly like a model except that it
has no visible component (ie modelResource, or shader) So, quoting from
your previous message:
> The solution to the rotating outside of the model (there's probably an
easier solution to this part of the problem, but my solution helps solve
then next part too) is to have an invisible parent model and translate the
vane away from that (monospaced font used here):
Just change that to "...have a parent group and translate the vane away from
that"
> by rotating that the child vane part will swing nicely. That solves the
swing vane part, but to solve the connecting to the next vane I made another
invisible model that is also a child of the first invisible model:
Would change to "...I made another group that is also a child of the first
group:"
> The @ swings along with the vane. Now all that's needed is to set the top
invisible model to the location (but not rotation) of the previous vane's
bottom invisible model. The whole of this vane is then pushed forwards, or
backwards, or up or down, according to what all the previous vanes are doing
at the time.
And finally this would change to: "...Now all that's needed is to set the
top group to the location (but not rotation) of the previous vane's bottom
group..."
