Question 1

Which modifier binds a character mesh to its skeleton so the bones deform the geometry?

Accepted Answer

Skin

Answer

The Skin modifier assigns vertices to bones with weights so the mesh follows the rig.

Question 2

What does 'envelope' refer to in the Skin modifier?

Accepted Answer

A capsule-shaped influence area defining how much a bone affects nearby vertices

Answer

Envelopes are capsule volumes around bones that determine vertex weighting falloff.

Question 3

Why is consistent polygon density important across a character intended for animation?

Accepted Answer

So deformation is even and joints bend without pinching or stretching

Answer

Even polygon density gives smooth, predictable deformation across the whole body.

Question 4

What is the typical purpose of adding extra edge loops near a character's elbow or knee?

Accepted Answer

To support clean bending and preserve volume during animation

Answer

Supporting loops at joints help the mesh keep its volume and bend cleanly when animated.

Question 5

Which approach helps prevent volume loss (the 'candy wrapper' twist) at a character's wrist or shoulder?

Accepted Answer

Adding sufficient loops and proper weighting/twist bones

Answer

Enough geometry plus good weighting or twist bones prevents the collapsing twist artifact.
