How to render polylines

In The Flesh

I've been experimenting with the "Convert Ribbons to Lines" and "Convert Tubes to Lines" options under the Edit - Object - Geometry menu.

The commands execute correctly and the viewport displays the converted lines. Line width settings are added under the surfaces pane. However no line settings are added under the parameters pane, and the lines don't render in either the iray viewport render or a full render.

I had a look at the Generate_Polyline_Wireframe.dsa sample script availble here: http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/geometry/generate_polyline_wireframe/start

I see that a Line Tesselation modifier is able to be added through scripting, so I tweaked the script to the following:

This does add the Viewport Line and Render Line Tessellation Sides properties to the converted lines, but they still don't show up in renders. I'm not suprised, because my scripting skills are very basic so the edits I did are a complete hack job.

Any ideas what I'm missing?

I have tested in both the last 4.11 release, as well as the last 4.12 beta.

TLDR: How do you get lines to be renderable in Iray when using the "Convert Ribbons to Lines" and "Convert Tubes to Lines" options under the Edit - Object - Geometry menu?

Are the too thin? Maybe make the material glow (brightly) and see if it produces light.

I'm trying to do something similar. It's been a year, but maybe we can put our heads together.

I think either you were a bit overzealous in ripping things out of the script or the script has been updated because nSides and nWidth are being defined and initialized, but the script as you presented it never actually does anything with these values. The original script has 4 stanzas in between where you declare nSides and nWidth and where you add the modifier that got deleted and they look like they were the lines that would have honoured the sides/width you wanted.

This is somewhat fixed, at least to thee xtent of not showing the email.

@UncannyValet No, sorry, I am focused on the opposite direction, i.e getting content out of DS, not into it.

Thanks for the heads up, fixed it now!

I did end up making some progress, but I lost a hardrive recently and been out of the scene working on other projects for a while now. Hopefully I'll get back to it eventually.
