nHair > Make Selected Curves Dynamic

 
 
 

Turns the selected curves into dynamic curves.

nHair > Make Selected Curves Dynamic >

Opens the Make Curves Dynamic Options window.

The following options let you model the curves for your hair before creating their hair systems or constraining them to a surface.

Attach Curves To Selected Surfaces

When on, the selected curves will attach to the nearest selected surface.

The follicle of the resulting dynamic curve will attach to the nearest point on the surface to the curve’s start CV. If you want to attach the selected curves at their opposite ends instead, select your curves and then select Surfaces menu set > Edit Curves > Reverse Curve Direction before making your curves dynamic.

Attach Curves To Selected Surfaces is on by default.

Snap Curve Base to Surface

When on, the start CVs of the selected curves will snap to the selected surface when the curves attach to the surface. This gives you a margin of freedom when drawing and placing your curves.

If there are hair curves already attached to the selected surface, the start CVs of the selected curves snap to the surface’s current follicle locations.

Snap Curve Base to Surface is only available when Attach Curves To Selected Surfaces is on. Snap Curve Base to Surface is off by default.

Exact Shape Match

When on, the shape and position of the selected (input) curves and their dynamic (output) curves will match exactly. The output curves inherit the Degrees of their input curves, and they also inherit the number and position of their input curves’ CVs. The input curves are rebuilt as Degree 1 curves. Exact Shape Match is on by default.

Note

You can only generate exact dynamic curve collisions with Degree 1 output curves. As such, we recommend that you do not turn on Exact Shape Match if you want exact dynamic curve collisions.
