Fiber の性質を決めるアトリビュートの一つ

ドキュメントやノードでは Fiber strength と呼ばれる

summary

When on, generates the fiber scale force that is applied to your muscle’s tetrahedrons when it contracts (activates). Fiber strength determines how strongly the muscle is squeezed. When and how much a muscle contracts is determined by muscletension (from the Muscle Flex SOP node) as it functions as a multiplier for Fiber Strength. The direction in which this scaling factor is applied to the muscle is determined by the Fiber direction (v@materialW).

f@muscletension determines what percentage of fiber stiffness is used at any time.

With a fiber strength of 0, the muscle does not contract and is always limp. With a fiber strength of 1, the muscle fully contracts. If you want one muscle to have a stronger reaction to the fiber scale force and another muscle to have a weaker one, then vary the fiber strength across your muscles.
