Set strands shape tube does nothing

[labbejason]

Hi world,

Just wanted to check how to use a `set_strands_shape` node to work as a tube shape. Right now it looks like it does nothing. Not sure if this is a bug or not?

Thanks!

It's not a bug, it's just that the mode doesn't do anything at the moment.

As an alternative, you could use extrude_strands from MJCG_compounds. It has a tube extrusion mode so you can generate a mesh out of your strands.

The viewport won't render tubes yet.  If you have a quite recent version of Arnold (I tested with 4.1.1), it should work, however.

It’s primarily to set the render time curves in arnold to tube shape for cylindrical shading (if you are doing hair/fur).

Gotcha, thank you guys.

Maxime, I was already using your extrude_strands so looks like I'll stick with it! Awesome job on it, by the way, it works very well.

Hey bro i meet the same problem and i dont see "extrude_strands" in my bifrost

Hi,

The extrude_strands compound is not one of the ones included in the default installation of Bifrost. It was written by Maxime Jeanmougin (mjcg91 on this forum) and is included in his MJCG compounds pack. You can download that here. For information about installing compounds, see these instructions.

I hope that helps.

its 2026 do we still not have a native node in bifrost for Strand extrusion ?

no yet, but you can use the extrude faces to do it but is not as straight forward as the the extrude strands from Maxime.

With the extrude faces you can use the extrusion path option for it.

hopefully soon? but thanks for the workaround, good to know there is a extrusion path option

Hopefully, it def would be nice to have a sweep inside BF.
