Mirroring Lattice Deformer

Introduction to Maya - Modeling Fundamentals Vol 1

This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

I just created a lattice around a very specific set of CVs on the left hand of a character, and now I'd like to create a lattice for the exact same points on the right hand. Is there any way to do that?

You'd probably just want to delete the unaltered side of the model, duplicate the altered one, and mirror it to form the other side.

Hi. I tried shift-selecting the hand and the lattice and then duplicating them by using Edit > Duplicate with -1 on the x axis. The hand was duplicated and the duplicate appeared where I wanted it, but the duplicate of the lattice appeared right on top of the original lattice.

Then I started over and I tried grouping the hand and the lattice, and duplicating the group. The hand and the lattice were mirrored properly, but the duplicated lattice was not attached to the points on the duplicated hand that the original lattice was attached to on the original hand. Any ideas?

are you using the lattice as a modeling tool? If so, after making the change with the lattice, delete the model's history, which bakes the lattice's change into the model, and then mirror that change fo the other side of the object.

ah

in that case, you're just going to have to redo the lattice. It's easier to recreate it then to try to duplicate it over, in my opinion.

what page? That seems strange. Skeleton rigging is the most used way of animating a character.

Ok, in that section, he's applying a lattice there because he's using a multi-patch nurbs model. If you're not using Nurbs, I wouldn't worry about doing that.

The lattice in question is just a simple lattice. You should have an easy enough time of creating an identical one on the other side. He doesn't actually use the lattice for animating. He uses it to keep the multi-patch together when bending the thumb joint, but he still animates using bones like normal.

This can also be done with flexors when rigid binding. A flexor is essentially, a lattice.
