How do you decide where to place supporting edge loops in a model?

Asked on Nov 10, 2025

Answer

Placing supporting edge loops is crucial for maintaining clean topology and ensuring smooth transitions in your 3D model, especially when preparing for subdivision. Supporting edge loops help control the sharpness of edges and define the model's shape more accurately.

Example Concept: Supporting edge loops are strategically placed near the edges of a model to control the smoothness and sharpness of surfaces during subdivision. By adding these loops close to the edges, you can prevent unwanted deformation and maintain the intended shape of the model. The distance between the supporting edge loop and the main edge determines the sharpness; closer loops create sharper edges, while further loops result in softer transitions.

Additional Comment:

Consider the purpose of the model and the level of detail required when deciding on edge loop placement.
Use supporting edge loops to maintain edge definition, especially in areas that will be subdivided.
Ensure edge loops follow the natural flow of the model to maintain clean topology.
Test the model with subdivision to check if additional loops are needed for desired sharpness.
