Use the Paint button to change the weight of the spring vertices.

Adding Forces and Deflectors
To see the effect of the Flex modifier, you need to add some motion to the scene. The flex object flexes only
when it is moving. One of the easiest ways to add motion to the scene is with Space Warps.
The Forces and Deflectors rollout includes two lists: one for Forces and one for Deflectors. Below each are
Add and Remove buttons. Using these buttons, you can add and remove Space Warps from the list. The
Forces list can use any of the Space Warps in the Forces subcategory (except for Path Follow). The
Deflector list can include any of the Space Warps in the Defectors subcategory.

Tip
When you add Space Warps to the Forces and Deflectors list for the Flex modifier, they do not need to be bound
to the object. n

Manually creating springs
The final two rollouts for the Flex modifier are Advanced Parameters and Advanced Springs. The Advanced
Parameters rollout includes settings for controlling the Start and End frames where the Flex modifier has an
effect. The Affect All Points option ignores any subobject selections and applies the modifier to the entire
object. The Set Reference button updates all viewports, and the Reset button resets all the vertices’ weights
to their default values.
