Just learning here... I created a model in Makehuman and imported it into Blender. When I pose the model I get really ugly creases where the mesh appears to overlap:

How do I clean this up or avoid it? I'm not worried about animating or anything I just want it to look smooth.

Typically its best to first attempt to resolve the issue by weight painting.

That is to adjust the weights around the joint to improve the deformation.

  • Adjust weight values by manually painting.
  • Use the smooth tool to automatically re-distribute weights (new in 2.76), eg: smooth result
  • Try the 'dual quaternion' option in the armature modifier
    (helps avoid volume loss),
  • When weight painting can't quite resolve all artifacts,
    try the corrective smooth modifier (new in 2.75)
    corrective smooth

  • Corrective shape keys
    Using a shape key to manually correct the distortion. While its involved to setup, it can be driven by bone and gives most control, This is typically used for more advanced rigging.

  • $\begingroup$ Thanks. I don't have the "corrective" smooth modifier (not sure why) but the regular smooth modifier appears to releave some of the distortion. I will play with the weight / quaternion values as well once I'm further along. $\endgroup$ Commented Jun 24, 2015 at 20:36
  • $\begingroup$ @mister martin, its in 2.75 which isn't released just yet, but suggest trying the release-candidate, since I think it does exactly what you need (assuming some simple tweaks to weights don't resolve). $\endgroup$
