I made a character and skinned and rigged him, and used automatic weights. When I move the upper bone in arm the mesh gets twisted and weird.

when i move the arm bone this weird thing happens

  • $\begingroup$ Possibly a scaling or rotation problem. Check that both your mesh and armature are 'scale and rotation applied' (use ctrl+A then rotation and scale). Once done reparent your mesh with the armature. If it is not that, please upload your file here blend-exchange.giantcowfilms.com ... and another simple reason here is that you have turn the bone too much... so the mesh is twisted and no more... $\endgroup$

  • $\begingroup$ as it seeems its not a "scale and rotation problem" so i will go with the fact that i have turned the bone too much. But if thats true how can i make working hands that dont get messed up when i move them much ? $\endgroup$ Commented Aug 2, 2016 at 17:40

When a real human arm moves up, this is in this way :

Not in this way :

I think this is the main problem here.

  • $\begingroup$ okok i get it :D now i will go make a new caracter with balls for shoulders to test if the arms will be more flexible xD thanks a lot. every time i have to post a question in this kind of site i am like wow why are they helping me ? these people are amazing $\endgroup$ Commented Aug 2, 2016 at 18:14
  • $\begingroup$ @IAmTehPotatoe, maybe because 3D modeling is really cool and sharing what we know is a way to share this cool thing ! And yes you can make balls for articulation for instance in this kind of approach fr.pinterest.com/pin/341358846731315353 $\endgroup$

  • $\begingroup$ @IAmTehPotatoe, no ! Don't stop dreaming or you will too soon become older than you are ! and they are not all 3D models here but they could be (was just to illustrate what you can do with ball articulation approach) $\endgroup$
