Hi all,

First post here. I'm a relative newbie with Maya, been learning for roughly 8 months so I may be missing something very simple. I've just finished modelling a robot and after scouring the net I decided to follow this tutorial for making the tank treads on the robot:

https://www.noir.org/tutorials/Xen%20.../treadtut.html

Seemed like the best solution for me without having to delve into any scripting or nCloth. Will only be used for forward/backward motion. This worked fine on the first tread but then when I came to grouping and then duplicating I've run into a few issues. When trying to move the 2nd set of treads over to the other side I'm getting double translations. I'm not sure whether I should be grouping everything (the track objects, the nurb circles and the lattice) and then moving the whole group or moving the lattice? If anyone has any experience with this tutorial I'd really appreciate any help?

Thanks,

Greg
