How can edge flow be planned to improve joint movement in animated models?

Asked on Nov 06, 2025

Answer

Edge flow is crucial for ensuring smooth joint movement in animated models, as it dictates how the mesh deforms during animation. Proper edge flow aligns with the natural movement of the model, reducing distortion and maintaining clean deformations.

Example Concept: Edge flow refers to the arrangement of edges and polygons in a 3D model that follows the natural contours and anticipated movements of the model. For joint areas, such as elbows or knees, edge loops should be circular and evenly spaced to allow for smooth bending and deformation. This helps maintain volume and prevents visual artifacts during animation.

Additional Comment:

Plan edge loops around joints to follow muscle and bone structure.
Use quads instead of triangles for better deformation control.
Test deformations early in the modeling process to identify potential issues.
