Changing pivot center midway through animation

[vijaykiran]

Hello,

Is it possible to change the pivot center of an object midway through an action sequence?

For example, I would like an object to have a turn radius of 30 for a spin action. The object then moves forward for a bit and then takes another spin action only this time it should have a turn radius of 15.

How can this be possible?

Thanks,
Vijay.
