Constraining wires to moving geometry ( Alembic)

[sophie95]

Hi,

I’ve been approximating a hair simulation using wires (placed manually as NURBs curves), the idea is that I would constrain them to imported alembic skinned animated geometry and then export the result back to Maya.

However, I’m having issues constraining the wires to the geometry. I’ve tried using an sbdconstraint and wireglueconstraint, but neither of these have any effect.

The ideal solution would be the ability to simply constrain the roots of the wires to the closest point on the surface at bind time and then stick there regardless of where the alembic geometry ends up, as extracting the proper xforms for the head movement is another issue I’ve ran into so far.

Any advice is helpful,

Thanks,

Sophie
