just trying to understand the logic,
so if i extrude end of the bone chain to create the hip, its a separate bone. and i have to parent it to the spine.
but if i extrude from middle of the chain of bones, like the controller bone at the ankle and bone at the knee that acts as a ik pole, i have to separate it. why are they not unparented~ like the hipbone
why is that so ?
Not sure, but I think because it’s a parent bone, with no relation to a bone chain (otherwise it is a child). if a child then it related to the bone chain?
I know I’m late to the conversation, but I hope this helps.
It depends on if you extrude from the head(Large side of octahedral) or the tail(Small side of the octahedral). In the case of the pole target you are selecting a connected tail and head which acts like extruding from the tail. With the hip bone you are extruding from the head.
