Properties[edit]
Property group 'Cloth'[edit]

bEnableClothBendConstraints[edit]
Type: bool
Modifiers: const
Enable constraints that attempt to minimize curvature or folding of the cloth.
bEnableClothDamping[edit]
Type: bool
Modifiers: const
Enable damping forces on the cloth.
bEnableClothLineChecks[edit]

bEnableClothOrthoBendConstraints[edit]
Type: bool
Modifiers: const
Enable orthogonal bending resistance to minimize curvature or folding of the cloth.
This technique uses angular springs instead of distance springs as used in 'bEnableClothBendConstraints'. This mode is slower but independent of stretching resistance.
