How could I pin points on a vellum cloth, to an animated geometry ?

Recommended Posts

Hi;

To pin some points on a vellum cloth, to an animated geometry, I tried these steps:

1) I add a “Vellum Attach to Geometry” SOP.
2) I grouped boundary points (“pin” group) on my cloth geometry.
3) In “Target Path” on “Vellum Attach to Geometry” SOP, I set path of my animated geometry.

but it doesn't work !

 

Thanks for helping.

If you connect Animated OUT to the collision port of the vellum cloth node, specify the pin group on the vellum attach node and turn of collision on the solver, it should work.

Thank you "bonsak"; now it works but I need collision and when I turn collision on, the cloth behaviors strangely!

I find another solution, so I add a "Pin to Target" vellum node, but it needs that all point numbers be matched point to point (All Pin point numbers to all Target point numbers)!

In my scene points on cloth starts from 0 to 49, and on animated geometry they are from 1 to 50 .
How could I match these point's numbers?

You can use a sort node set to shift to offset your point numbering:

you're overcomplicating things too much..

If you look in Cloth, you'd see I defined 'Cloth' only for the patch. Technically you can leave it blank to define all as cloth (but later on you pin the 'drum' part of the geo), it will still work but..slooooooooow.

Hence to define only the patch part as cloth, then pin the rest of the drum as per user hand animation, much faster.
