A big problem when simulating hair and cloth with Motion Designer ( MD )in LW is that we can't control forces in the area we want. If we have something like a weight map controlling MD simulation it would be fine.
A MD blender is really necessary too. Sometimes we want to create an artistic pose with hair and clothes and MD does not allow us to control the shape.

See the problem:
If I set different MD parameters to different surface areas, one part will be forced to appart from the other. I can't smoth or make a transition between 2 MD sets. I always have to aply the same MD set to the entire cloth and the result is unreal.

I see that a low poly cloth with a big subpatch rendering division can create smoth transition between 2 MD sets at the same cloth, but this is not suficient to create a complex cloth simulation.

How can I solve this?
Is there a way to create a plugin to use weights controling MD?
Please, show me a solution.

export the md calculation as morph maps say, like every 10 frames ?

fiddle with them in modeler

use the morph maps to animate the hair.

dunno haven't tried it that way yet

Hey...Hi...I have been running into the same limitations...adding Weight Maps to Motion Designer would be insanely cool...in the meantime, I have resorted to breaking my object into several "parts" and using the part names to define the MD parameters so you could theoretically have different additive cloth properties on every vertice if you wanted, even with a single surface object...the catch with this approach is that is time consuming to prepare the model and time consuming to set up all the various parts with different ranges...there may be other drawbacks, but I have only tried this with relatively simple scenes...and now that I think more about it I would imagine you'll have roughly the same trouble with this approach as you are already having...so good luck with that...let us know if you come up with something better...wishing the best...from the void...j.p.rapscallion...

Thanks everybody for sugestions.
I tried some forms but I didn't get sucess. The simulation is still like a rubber cloth or moves too much.

I'd like to know where can I find the settings they used in these simulations bellow:
