I'm new to Blender and am having an issue with some joints wrinkling when moving the armature. In the attached image the left knee is exhibiting this problem, while the right knee is bending as I want it to. Weight painting doesn't seem to be helping (either heavily painted or lightly painted I still get the wrinkle).

All my other joints work just fine. Any ideas? I'm using Blender 2.80.

  • $\begingroup$ The mesh topology is bad in the left knee. Somehow you swapped the middle edgeloop and the lower one. Swap them back first, then try to repaint the weight. $\endgroup$ – FFeller Dec 17 '19 at 18:05
