In the demo there will be a number of ‘picker bots’ scanning and picking up discarded components.
Getting tracks working in Maya was relatively simple, using Motion Paths>Add to Motion Path.
However as is often the case this proved tricky to convert into a useable format for UE4.
Eventually I got around this by just bringing one animated tread into UE4, instancing it several times, and starting each instance to play at a staggered start time per tread. This worked really nicely and I think the result is as good as how it looked in Maya. I will need to talk to my tech expert to see if this is at all efficient but for now it will do.
