Ziva VFX v1.3更新日志：
Attribute zFiber.envelope also affects excitation due to zLineOfAction. Consequently, if zFiber.envelope is zero, that fiber will not contract.
Tissue tetrahedralization will no longer happen while zSolver is disabled. Pulling on zTet.oMesh while the solver is disabled will no longer work.
Make initial fiber endpoints work on meshes with multiple connected components. Previously, the fiber would be created and instantly cause an error in the scene.
Fixed bug that sometimes causes fibers to draw in grey when multiple fibers are selected.
Fixed bug that sometimes left the effect of a zFiber node even after the node was deleted.
Minor fixes to the undo/redo behavior of ziva, zPaintAttachmentsByProximity, and zMeshCheck MEL commands.
