I have been trying to scale my character which has many similarities to the mancandy and ludwig rigs. However, when you try to scale the root bone of the armature(which scales the mesh), the bones move out of the natural placement causing unwanted positioning and distortion. Both the mancandy and ludwig rigs have this same problem. Is there any way around this?
That particular problem comes from IK constraints, avoid those and you should be good, that, or disable them before scaling, and recreate after scaling if you really need them…
why are you trying to scale the root bone (to scale the whole model)?
are you doing this in pose mode or object mode?
if you are trying to scale the whole model try it in object mode
also check if you are scaling around the cursor instead of median point
