From the manual
Connect the source geometry (the geometry to deform) to the first input, the rest geometry (the initial shape of the control geometry) to the second input, and the edited form of the control geometry to the third input (this is usually one or more Transform SOP s, although you can use any editing nodes. You can also use the Edit SOP , although it can't be animated).
The first part I get , create a simple tube wire it into the first input on the lattice SOP. The second part I dont quite get “rest geometry ”. The example shows a bound SOP plugged into the second input why ? surely the cylinder is at rest as Ive not done anything to it, whats the reason for having this second slot that needs an extra node being the bound sop ? surely it would make better sense to have the entire lattice / bound SOP combined into one SOP. I understand I plug the edit SOP in the 3rd slot , but why not have a lattice sop plug into the edit SOP , creating a simple chain of operators.
In the mean time I created the nodes shown in th manual. Using the edit SOP I select some points on the lattice (s) , right click nothing happens , I then hit return and I get the global transform tool come up ,with nothing selected, I move it around and the values inside the edit SOP transofrm tab alter so I am inside the edit sop. Needless something like applying a lattice should not be this difficult it isnt in any other application! i
So any advice on the why the lattice sop is set up this way would be helpfull. Also how I am suppossed to get it working lol ….. the examples really dont help ….
