Collapsible Joint Topology

Ever get nasty deformations around a joint in your character? Learn to use triangles the right way in this quick tip video.

This allows the edge nearest the back of the knee to collapse, which takes the “pressure” off the rest of the mesh so that the calf and thigh will not warp when bending.

    Nice tip! Would be great to see tips or even tutorials a about the hip area in the same way. Especially in the front when the leg goes up.
