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.
You may already know this if you’ve been modeling characters for a while, but this technique was new to me.
Instead of using three edge loops to define a joint, you can use two triangles near the back as seen below:
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.
