The tyFlex modifier applies spring forces to mesh vertices based on their movement.
The tyFlex modifier is multi-threaded and has an internal cache that is only re-computed when necessary, making it a faster and more efficient alternative to 3ds Max’s built-in Flex modifier.
Stiffness: the stiffness of the spring forces. Increasing this value causes mesh vertices to attempt to return to their resting positions at a higher velocity.
Damping: the damping of the spring forces. Vertex velocities will be multiplied by this value prior to integration. Increasing this value decreases the rate at which vertex velocities accumulate over time.
Affect: controls the overall influence of spring forces on the resulting mesh.
Use vertex selection: when enabled, spring forces will only be applied to selected vertices.
Reset on mesh change: when enabled, the internal tyFlex cache will be reset when the underlying geometry of the object is changed.
Reset on setting change: when enabled, the internal tyFlex cache will be reset when a tyFlex setting is changed.
Clear cache: manually clears the tyFlex cache. Useful for when either “reset on mesh change” or “reset on setting change” are disabled and a mesh/setting change is made, invaliding the previous cache.
Force list: the list of forces that will contribute to the motion of mesh vertices.
X/Y/Z %: the amount of axial influence the forces will have on mesh vertices.
Multiplier %: an overall multiplier for the forces.
