Attach Hair To Ncloth

[robw]

Hi everyone!

My first post here...

I'm trying to build a rug with fringes at the sides, wich I would later animate by wind forces to make the rug lift from the floor. My idea was to make the fringes with Hair, and then connect it to a simple polygon cube wich I would apply NCloth to.

My problem is that the hair won't stay attached to the NCloth object. The rug happily animates by the forces, but the fringes just sits lazily where they were made, and thus come unattached to the rug.

I've tried plenty of grouping and parenting, and also a number of hair constraints/"normal" constraints. With hair constraints it seems like the rug is obeying the hair, but in my case I want the hair to follow the rugs animation.

I'm a little stuck here. I'm new to hair and NCloth, so if anyone can help me out on this, I'd be very glad!

Thank's in advance,
Rob

Problem solved.

In Hair->Create Hair Options i disabled Grid and chose At selected points/faces instead. Worked like a charm

The key thing is to apply hair to the rug after you have made it into nCloth. If you do it before then the hair is relative to the cloth input, not output mesh. The input mesh is your original mesh that becomes hidden when you create the cloth.
(creating in a grid layout or at points should not make any difference)

Dear Duncan,

The fact that you go out of your way to answer questions about Maya in a forum like this, is yet another reason why Maya will always stand out as one of the best products ever made (if not THE best software ever made)

I also have a question along the lines of the original question in this post. I am rigging an arm that will flop around from an IK chain driven by a hair curve. I also need to add ncloth to the arm, to give it the look and feel of soft skin when colliding with other objects.

I setup the ncloth first and then skinned the same mesh with the hair driven IK chain. The computation time of each frame has gone way up but the arm does not seem to be reacting to the collision surfaces, it just pops through the other side.

Can you suggest something to allow this scenario to work as expected?

Thanks!

If you create nCloth then skin it the deformer will be applied to the output cloth mesh, which is after the simulation occurs(like deforming the cached cloth simulation). If you skin it first then make it nCloth it will simply flop with no deformation as you run the simulation( although the start frame position can be set by the deformer ). However input mesh attract will pull the cloth towards the skinned position. You could use this so that, for example, the arm squishes where it hits the ground, but otherwise follows the IK chain. However note that the cloth collisions will not "feed back" to the hair collisions, so the hair motion must handle the basic collision. With this you probably want to minimize jiggle by increasing the cloth damp. Also make lift/drag zero on the cloth(it is heavy meat, not tissue paper). You may wish to paint the input mesh attract so it is more rigid in some places. One other thing you could look at is "Connect Input Mesh to Rest Shape", especially if you don't want the skin to wrinkle as it deforms.
