Driving high res mesh by low res cloth object.

Hi,

I have a high polygon count model that I want to deform by a cloth object driven by a low polygon model that's part of a cloth simulation.

I know the rest state of the low polygon model, and I have the output SOP node for the deformed cloth simulation. I've created two merge objects to bring in the rest and deformed polygons into the high polygon SOP node, but that's as far as I was able to get.

I thought you could use the Deform SOP to assign the rest/deform geometry to the high polygon model, but I've been unable to get it to work. I think I need to use metaballs somehow, but I'm not sure.

Anyone have some advise on how to do this in Houdini.

Thanks,

Thanks, that did the trick, but I'm surprised it was done with a VOP SOP and that Houdini didn't have some already built SOP node to handle this. As it's a common requirement in most 3D apps.

EDIT: Sorry, I see it's done with attribute transfer which makes a lot more sense.

actually, if I´m not wrong, the solution in the video uses both, attribute transfer and three or four different VOPs. And yes...it´s far from a simple solution.

Of course, it works wonders :P

Lattice and wiredeform are things to try, but as the video states, sometimes they do strange things.

Edit: ah, yeah. The video actually states you could do this without VOPs and just attribute transferring the transformation matrix from the lo-res...which doesn´t make sense to me, because I would say you need VOPs for that. Is it actually possible to do this without VOPs?
