It determines the colour of the joint in the viewport

It defines the local rotation axes of joints, ensuring predictable rotational behaviour during animation

It sets the joint's influence on skin weights

It controls the joint's visibility in the Outliner

Adjusting the mesh topology for smoother deformations

Editing the interpolation curves of keyframed attributes to achieve natural acceleration and deceleration

Applying a normal map to the character's surface

Baking all keyframes to linear tangents

Joint-based facial rigging with driven keys

Blend shapes for phoneme-based mouth shapes

Lattice deformers for the mouth region

UV mapping with animated textures

It restricts all UVs to a single $$0-1$$ space, making texture painting more difficult

It allows the use of multiple UV tiles, enabling higher texture resolution and more detailed texturing across large or complex models

It automatically generates normal maps for the character

It is only used for hard-surface models, not organic characters

Using only rigid binding

Poor distribution of weights between adjacent joints and lack of support edge loops

Applying a normal map before rigging

Using only blend shapes for deformation

To create hard shadows; it should be brighter than the key light

To soften shadows and reduce contrast; it should be less intense than the key light

To provide rim highlights; it should match the key light's intensity

To illuminate the background; it should be the brightest light

They automatically generate skin weights for the mesh

They provide intuitive, non-destructive controls for animators to manipulate joints and deformers without directly selecting the skeleton

They are used to create UV layouts for texturing

They increase the polygon count for smoother deformations

It ensures the controller's transformation values are zeroed, preventing unexpected behaviour when setting or resetting poses

It increases the number of available keyframes

It automatically applies skin weights to the mesh

It changes the colour of the controller in the viewport

FK controls the end effector directly, while IK controls each joint individually

FK requires animating each joint in sequence, while IK allows the animator to position the hand and have the arm follow naturally

FK is only used for facial animation, while IK is for body animation

FK automatically generates keyframes for all joints

The mesh will not render in the viewport; this is fixed by deleting history

Blend shapes may not deform as expected after skinning, causing incorrect or double transformations during animation

The UVs will become detached from the mesh

The joint hierarchy will be broken

Single Chain is best for simple joint chains like fingers, Rotate Plane allows for pole vector control for limbs, and Spline is used for flexible chains like spines or tails with multiple control points

Single Chain is only for facial animation, Rotate Plane is for texturing, and Spline is for UV mapping

Rotate Plane and Spline are interchangeable, but Single Chain is only for static props

Spline is used for hard-surface modelling, while Single Chain and Rotate Plane are for organic characters

Increasing the polygon count in the torso

Adding extra support edge loops and using corrective blend shapes for problematic poses

Using only rigid binding for the shoulder joint

Applying a specular map to the shoulder area

It reduces the file size

It ensures the mesh's transformation values are zeroed and prevents unexpected deformations during animation

It automatically applies textures

It sets up lighting for the scene

Using only blend shapes for mouth shapes

Combining blend shapes for phonemes with joint-based controls for jaw and tongue movement

Relying solely on keyframed UV maps

Using only driven keys for all facial features

It allows updates to character models and rigs to automatically propagate to all animation scenes, ensuring consistency and efficient collaboration

It increases the polygon count for higher detail

It automatically bakes all animations

It is only used for rendering static images

They create smooth transitions between poses

They hold each pose until the next keyframe, making it easier to plan timing and spacing

They automatically generate in-between frames

They are used for facial rigging only

It simulates direct sunlight; it cannot create soft shadows

It adds contact shadows in crevices, but does not account for dynamic lighting or cast shadows from moving objects

It increases the polygon count; it slows down rendering

It is only visible in the viewport, not in final renders

Blend shapes cannot be used with joints; the solution is to use only one method

Deformation order conflicts can cause unpredictable results; this is managed by carefully setting the input order in the construction history

Joint-based rigs cannot animate eyes; blend shapes are used instead

UV unwrapping must be redone after rigging

Relying solely on a single front view image

Aligning and calibrating both front and side reference images in the image planes, and cross-checking proportions during modelling

Using only a perspective view for all modelling

Tracing over the reference image with the Paint Tool
