I have a generated mesh and set of bones from a makehuman model but it created two bones in the shin.

How do I merge the two selected bones into one bone but keep the skeleton intact, i.e. the knee and foot where it should be.

model with rig two selected bones should be merged

  • $\begingroup$ @David: Oh, so now we're putting bones in a blender? Out of context, that sounds really creepy! ;) $\endgroup$ – Mason Wheeler Oct 20 '15 at 15:46

    $\begingroup$ @MasonWheeler We also deal with severed monkey heads and such. $\endgroup$ – GiantCowFilms Oct 20 '15 at 15:46

The universal way to delete something in Blender and merge surrounding elements to a single object is to use Dissolve (Ctrl+X). It works for meshes, nodes, bones and grease pencil points.

    $\begingroup$ I like this better than Alt-M $\endgroup$ – Jaroslav Jerryno Novotny Nov 11 '15 at 18:29
  • $\begingroup$ Is there an advantage of doing it this way as opposed to the ALT M way? $\endgroup$ – Chris Stone Nov 12 '15 at 16:14

    $\begingroup$ @ChrisStone With this way, your model's weights are much less likely to get screwed up. $\endgroup$ – Bradman175 Sep 17 '16 at 4:37

With the two bones selected like in the picture in your question, simply press AltM.
That will merge the two bones and take care of the bone relations.

Or You could achieve the same thing in more steps by deleting the two bones, and "filling" a bone between the two ends that are left. Then going and editing the Bone Parent and checking Connected for the top bone.

  • $\begingroup$ Thanks a lot! I did try ALT M but I was in pose mode and I was wondering why nothing was happening, Doh! By the way, how did you make those neat little animations? $\endgroup$ – Chris Stone Oct 20 '15 at 18:03
  • $\begingroup$ @ChrisStone sorry if I never got back to to (or if I did you can just ignore this) Read What is the process for creating gifs for questions and answers? I wrote up my whole process there. $\endgroup$ – David Jun 4 '16 at 16:55
