Hair Stretch Constraint

C++ Source:

  • Plugin: HairStrands

  • Module: HairStrandsCore

  • File: GroomAssetPhysics.h

Editor Properties: (see get_editor_property/set_editor_property)

  • project_stretch (bool): [Read-Write] Project Stretch: Enable ther projection of the stretch constraint after the xpbd loop

  • solve_stretch (bool): [Read-Write] Solve Stretch: Enable the solve of the stretch constraint during the xpbd loop

  • stretch_damping (float): [Read-Write] Stretch Damping: Damping for the stretch constraint between 0 and 1

  • stretch_scale (RuntimeFloatCurve): [Read-Write] Stretch Scale: This curve determines how much the stretch stiffness will be scaled along each strand.

    The X axis range is [0,1], 0 mapping the root and 1 the tip

  • stretch_stiffness (float): [Read-Write] Stretch Stiffness: Stiffness for the stretch constraint in GPa
