Using standard 3ds Max scale transform tools, you can adjust a biped's posture by scaling the size of its links. You must be in Figure mode to scale the biped links. If you try to scale a biped without going into Figure mode, nothing happens.
To scale a biped that has a mesh attached to it by using Physique:
The biped and mesh scale together.
To reinitialize a scaled mesh:
Reinitializing a scaled mesh might be necessary if you use Initial Skeleton Pose in Physique. In this case, the mesh appears at its size before scaling. To correct for this, perform the following steps:
The mesh will get large because it is doubly scaled.
The mesh will shrink to the size you set during scaling.
