Reply To: Rigging issues!

I found a some issues with the rig in just a few minutes. Here are the problems I found so far.

1. The following bone axis are aligned incorrectly. The Z axis should be pointing upward instead of downward. This can be fixed by setting the roll to 180 in edit mode.

MCH_Toes_FK.L     DEF_Toes.L    DEF_Foot.L    Foot_FK.L     Toes_FK.L     Foot_tweak.L

2. Both Foot_heel.L and MCH_Heel_Roll_01.L have their rotation order set to XYZ and they need to be set to ZYX.

3. On MCH_Heel_Bank_01.L, MCH_Heel_Bank_02.L, and MCH_Heel_Roll_02.L on the limit rotation constraint you need to check Legacy Behavior.

4. On MCH_Sheen_02_tweak.L the copy loction.001 and damped track constraints should be pointing to foot_tweak.L. Also the Damped Track should be set to Head not tail(Head/Tail set to 0 instead of 1). You also need to adjust the copy location.001’s influence to 0.125 

I stopped looking at this point. You started off with problems from before you even started rigging. The shorts, shoes, and shoe strings are all rotated and scaled in object mode. This could have been fixed by applying rotation and scale(Ctrl+A). Then your Rig was moved(Location) and scaled in object mode. Location and rotation should be all 0 and scale should be all 1s before you start putting constraints or skinning. This is why you need to change the influence to 0.125 instead of the 0.5. I’d recommend starting the rigging over. So you don’t have to redo all of the weight painting you can do the following. 

1. In object mode, select everything and ctrl+a->Rotation and Scale. 

2. Select just the rig and press ctrl+a->Location.

3. Tab into edit mode make all bone collection visible(Eye icon open) except the root and DEF collection.(Eye icon closed)

4. In edit mode select all and delete(X->delete bones).

5. Switch to pose mode, make DEF and root collection visible, select all, and press Ctrl+alt+C to remove all constraints.

6. In edit mode on the DEF_Toes.L and DEF_Foot.L set the roll to 180.

7. In object mode, select the shorts and adjust the solidify modifier to fix the thickness. I used 0.01 instead of the 0.1.

8. Start rebuilding the rig from there.
