How to control Strand extrude orientation?

[absoluteKelvin]

Hi Bifrost wizards, I need your assistance please.

Im trying to figure out how to fix twisting on a complex curve, especially around the sharp turns. setting the up vector to  0 1 0 seems to fix parts of the twist, but still getting flipping on some areas. Curve has been resample in bifrost.

Those rotations are hand made. Even in real world.

I see no easier way than doing it by hand. If you force it on bifrost you need for each turn a length and a rotation value. This would take more time than modeling it by hand.

Ah I see, I was hoping there is a way to set rotation values to specific cv/points. Main reason is I want to keep the mesh adjustable, in terms of segments and scalable since its a curve/strand.

Thanks for the info Christoph
