Question about French Crop Hair

Question about French Crop Hair. I submitted a ticket, but maybe someone here might now while I await a response from daz.  Is this supposed to be a dforce/strand hair? Why are none of the hair setting available? I need to be able to show lines in viewport and have the tessellation settings for dforce hair to render in octane render.

    No, it's mesh hair using modelled strands as far as I can see.

    Interesting, I wonder why I can't get it to render in octane then...

    It is lines, not polygons - and it has nearly 3 million vertices.

    So it's not lines from the strand based editor?

    Would that make it more memory intensive?

    Not all SBH is made in the SBH Editor.

    Iray Curves are an Iray feature, no? can you usually render curves/splines/polylines in Octane? Does SBH with Render Tesselation Sides of 0 or 1 work in Octane?

    Does this product have a Render Tesselation Sides option under parameters? Does adjusting it to a higher value help?

    No tessellation settings in parameters. I can usually render this type of hair by turning up the settings for the viewport but since there are none I can't.

    It is just lines, so it is possible Octane doesn't support them (vertice coinnected by edges, but not actual polygons). It would be a bit of a surprise, but it is possible.

    Actually, one of the previous developers for the octane plugin did inquire about this https://www.daz3d.com/forums/discussion/602706/uv-sets-for-strand-based-hair#latest (they don't work at otoy anymore though).

    Currently, the strand hair in daz can't be converted to octane's hair curves (so we can't even use octane's hair shader) but somehow we have them in iray? So the workout around is having to to crank up the viewport tessellation to be able to view in octane's viewport. So, if iray can do it, it should be possible in octane, but apparently there is some sort of secret.

    You might be able to frankenstein the later sections of this code to get a Render Tesselation Sides modifier onto that polyline hair: http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/geometry/generate_polyline_wireframe/start

    I could never figure out how to get it to work.  I mean, I can add a Render Tessellation Sides parameter to paramaters tab, just cant get it to do anything.

    You need the real property to exist, just adding a new slider will not do anything.
