Making a lattice that works on two referenced file (character and car).

[sheldon7EVSV]

So... I have referenced into a scene, both a car, and a character. I would like the character to move with the car, and to be influenced by the lattice as well.

I have used the parent constraint to have the character move with the "car" I am using, and that works fine... until I try to use the lattice controls (using clusters). Then the character is torn apart. I don't think I have used the correct method to parent the character to the car.

What is the CORRECT method of doing this, so that I can both move the character with the car rig, and deform the character sitting in the car rig?

Thanks for your help!

is the lattice base following the main control?

Hi Baboonian. If I understand your question correctly no, the lattice does not follow the main control of the car. i.e. It does not move when the main control of the car moves, but it does encompass the car controls.

Hi)

I mean "ffdBase". It should follow the car together with "ffdLattice".

And requires a direct connection to the cluster transform channels. They shouldn't be constrained or parented to prevent a double transformation.

Oh... I see what you are doing (finally). I kept the Parent Constraint between the Character and the Car that I had, but I just put the lattice on the geometry of both (not the controls for the rig of the character and the car).

Your movie was most helpful once I figured out what the analogues were to my scene. 😀

• pCube1 was the analogue of both models
• joint1 was the analogue of both rigs (including the parent constraint between the character and the car)

I can now control the space inside the lattice for the car and the character without doubling the deformation on the character (as I wanted). If I want to "drive" the car, I can move it the usual way, and put ffd1Lattice in the same place (or I can drive through it, if I like).

The CONTROLS for the rigs can be moved onto the new position that the I have the ffd1Lattice and the geometry by selecting the ffd1Base and positioning them.

Thank you very much!
