Strands extrusion vertex order.

Hi. Is there a way to change a vertext order of extruded strand (ribbon type)?

 

I want to construct a procedural object where curve controls an extruded ribbon, and its boundary edges are used for other extrusion.

 

In non-procedural way I regulary extrude 6 sided cylinder cap using curve. Then I select 2 edge loops of extruded object, convert them into nurbs curves and use this curves to extrude other smaller cyllinder caps.

 

I tried to illustrate of what I mean in attached images.

Or maybe there is some other approach?

Here something you could do. It will only work with a single input curve though. If you want to apply the same setup on multiple strands at once, you'll have to play with the point position of the ribbon mesh and construct a strand_offset.

Thank you so much! This is really what I need.

Sorry, I'm really dumb in programing, and its my first steps with bifrost graph. I've also tried to learn maximejeanmougin's article before asking. Couldn't figure out how to use array_sequencer in my task by myself.

 

Also, can I ask you if there a simple solution in current compound to make bridge connections for those caps?

You can download the latest version of my compound pack. extrude_strands as new parameters to cap starts and ends of tubes.

I've installed the latest version of MJCG compounds. I'm affraid that I meant this kind of bridge cap, where both extruded rails are connected.

extrude_strands is not meant to be used for this, but you could modify your strands to make the effect you want and then feed it into extrude_strands
