Variable cloth stiffness?

[Janmansilver]

How do I vary the stifness of cloth? All the documentation and examples I can find are for old versions of Houdini, the new Cloth solver is a mystery. I would like create/paint attributes and the points the tell the solver that these areas should not bend as much. But how is this done?

Create a group / groups (however you need - paint, selection, etc.) then drive the stiffness with them

@Janmansilver not sure where you are looking but the documentation has all this and is up to date.

The primitive attributes that multiply the Stretch, Shear, Weak Bend, and Strong Bendmodels are:

Parameter	Type	Name
Stiffness	float	shellstretchstiffness
Damping	float	shellstretchdamping
Shear Stiffness	float	shellshearstiffness
Shear Damping	float	shellsheardamping
Weak Bend Stiffness	float	shellweakbendstiffness
Weak Bend Damping	float	shellweakbenddamping
Strong Bend Stiffness	float	shellstrongbendstiffness
Strong Bend Damping	float	shellstrongbenddamping

Thanks I used  shellstretchstiffness  with an attribute create and a paint sop and then an attribute promote points to primitives and this seems to work just fine. Thanks. :-)

Does anyone know where are those control attributes now in H16 ?
Testing my old files from H15 and they are just not working anymore, also they took it of from the new documentation ?

BTW found the new updated cloth object in H16  just horrible, unpredictable and uncontrollable comparing to H15. Why is that happened, may be just not to update something that just worked fine ?
