This tool is usually used with dynamic Wire Objects such as fur. It allows you to run the simulation until gravity has naturally settled the curves, then reassign the starting point in the simulation so that you no longer see the initial effects of gravity on your objects.

1. Run the simulation for your Wire Objects and stop it at the point you want to set as the new initial pose.

2. Click the Set Initial Pose tool from the Wires tab.

3. Select the dynamic objects to set the initial pose for and press Enter to confirm your selection.

4. Click back to the first frame on the animation playbar and run your simulation again to see your changes.
