Determine the Shape of the feet
The feet of the robot are essentially a metal cage. Using a cube or square stamp, select the line brush mode. Begin to create the base shape of the cage, remembering to adjust the layer resolution as needed to ensure that the edges are crisp. Keep adjusting the position of the sculpt’s feet to ensure that the pose maintains balance. To do this, select the foot or leg layer you wish to move, then using the inner grips of the controllers, you can move that layer around independently from the rest of the model.
