Each weighting envelope is a capsule with an inner and outer gizmo. The vertices that fall outside the gizmos are not at all affected by the bone movement. NOTE If you are using the Physique modifier, you should also save your file before you put the modifier on the mesh.

You need to adjust each envelope so that it only affects the required portion of the mesh. The general workflow of skin vertex weighting is to go through the bone envelopes and adjust the radius of each end of the capsules, as well as reposition the capsule ends to fit within the length of the biped skeletal bones. It provides a more controlled method for creating muscle bulges, and for keeping elbows and knees from crimping when the angle between the bones is very sharp.

Just as our own skin is moved by the motion of our bones and muscles, your mesh character is animated by means of a skinning modifier that deforms the mesh according to the rotation and position of the objects in the biped hierarchy.
If you are using the Physique modifier, you should also save your file before you put the modifier on the mesh. Before applying Skin to a mesh, make sure the bones fit nicely inside the geometry. At the time the mesh is skinned, vertices on the mesh are associated with one or more bones via a weighting system. To make the biped control the mesh and move it around, you have to associate the biped with the mesh.
Publishers of technology books, eBooks, and videos for creative people.
The initial envelopes, and thus the vertex weights, depend on the size and orientation of the bones. See All Related Store Items. In addition to skinning, the Skin modifier also allows the deformation of character-mesh objects by associating the bones with mesh vertices.
At this time you can also add additional cross sections to the envelopes to allow for finer control. Like Biped, Physique is now included with 3ds Max and is essentially the same software that originally shipped, with a few bugs fixed. Another use for Skin Wrap is to employ spline objects to drive the animation of a mesh. If your objects have been grouped, we recommend that you ungroup them before applying Physique or Skin.
This is accomplished through a process called skinning.

The vertices between the inner and outer bounds are weightedor somewhat affected by the bone movement. At first it lacked some of the sophisticated features of Physique, but over time it has continued to improve.
Notice that no change occurs in this mesh. Skin Wrap works at either the vertex- or face-deformation level. Often the biped will jump to a new location when Figure mode is turned on. However, unlike Physique, Skin allows you to mirror the bone-vertex assignments from one side of the body to the d3s. Skin Morph allows you to fine-tune the way vertices respond, based on the angles between bones. The vertices that fall outside the gizmos are not at all affected by the bone movement.
The vertices within the inner gizmo are completely affected by the movement of the bone. This is done using the capsule-shaped envelopes, which control specific vertices.

You can do this in 3ds Max 8 through a process called skinning. This means you can set up the animation with a low-poly mesh and fine-tune it with a faster playback speed before switching to the high-poly mesh for the final rendering. This happens when the bones are wider than they are long. This chapter is from the book.

The Skin modifier also includes the biper to define bulges based on the angles between bones. A vertex that falls within the capsules of more than one bone receives appropriate weights from each bone.
In this way, each part of the biped acts as a bone. Meanwhile, giped has stopped on Physique. Each weighting envelope is a capsule with an inner and outer gizmo.
