Does Layer structure matter for Body / Limbs?

• Sometimes the hierarchy matters, sometimes it does not, so there is not a blanket answer. For example, taking a layer and putting it in a group generally won’t have much effect. You just have to work out a combination that statifies all your needs.

Examples

• The order of layers, as you point out, matters for depth arrangement. That is more top to bottom in PhotoShop/Illustrator rather than depth in the hierarchy. But sometimes you have to change the hierarchy to achieve what you need. An example of this is rear long hair that goes behind the body. If the head is independent and in front of the body, but you want long hair behind the body, you often create a separate top level group so you have Head, Body, Rear Hair - otherwise the rear hair won’t go behind the body.
• The hierarchy structure matters if you want to limit the scope of some behaviors.
• Dependence matters as well - the layers with and without their “+” symbol. Sometimes the layer structure does not matter uuntil you hit an indepdentce layer (one with a leading “+”). If you have a few dependent layers with a tree structure, they are all considered as one node by CH

Arm positions generally don’t matter that much - that is, the arm will generally keep working. The but the structure does matter if the layers move and you care about how the arm moves. But profile layer positions matter more. Eye structure layers can matter a lot. Mouth positions matter.

I am not sure if that is useful - in this case “it depends”. It can matter, but does not always matter.
