I'm Confused With The Parperairplane Shadow In Duncan's Tutorials

[mayacner]

Duncan,would you help me producing the parperAirplane's shadow in your tutorials,I even don't know how to constraint the shadow to the ground.it seems that the traditional solution doesn't work for nCloth,I notice that you connect the outputMesh and the inputMesh,however when I also do it,it doesn't work as yours,it keeps the ralative distance.then what's the problem?
in addition I guess the shadows produced by first duplicating the plane and scaling them to 0 in Y,am I right?and it seems that you do the constraint without the methods listed by the ncloth menu,is it accomplished by scripting?

thanks very much in advance

The normal duplicate doesn't have any history. However one can simply do
"createNode mesh"

Then connect the worldmesh output of your mesh to this new one. This provides a duplicate with history. One then simply scales the transform to zero in y on the duplicated one and assigns a black partially transparent shader for the shadow. (the mesh from createNode will initially not be assigned any shader and thus will only draw in wireframe)
