Hello
I wonder how to specify the driven elements or segments with tags in the autorig component node, when it uses the spline component source.
For example I have two joint chains and want to tag some of the joints as splines, on side has the tag spline_A the other Spline_B, and now I want to use these tags to be used in the autorig component. the desired result would be two sets of spline controls for the tagged joints.
What would be the correct syntax in the driven field?
I can use the joint names in the right order to get spline controls, but if tags are possible it would be great

thanks
Martin

#tag works when it is also available on the Base.skel. I thought it would be only needed on the Guides

I thought this too, that you added tags, parms and promotes to a guide skel and it was an additional skeleton for that purpose. The language around APEX is really confusing to me.

You can tag all of the spline nodes "spline" and use that in the Segments parameter (as "spline" not #spline).

Segments and driven are performing the same function. The segment will run over multiple and the driven will only run once.
So if you want multiple spline setups use segment. That being said, you can also use the segment for a single spline setup.
It will only read the tags from the guide skeleton.

In your setup you can simply add spline* to the segment field, segments are by default seen as tags and dont need the #.
Internally this will run each tag in a loop and set up a spline per tag and name them.
