Moho (Anime Studio) Tutorials : Control Bones From Parent Layer

1. Create your bone

In this example setup there is:
Parent bone layer (main bone layer)
--Child bone layer (bone layer)
----Image layer (hand.png)

Create a bone in the child bone layer that you want to be controlled in the parent layer, and give it a unique name. (eg. hand)

2. Attach the script

Double-click the bone layer to launch its settings.
Click on the embedded script file option and select the script (NESTED BONE CONTROL SWITCH.lua) -- This file is in the supporting documents


Notes:

This script works for smartbones and it's independent of grid location so you can put bones where ever the heck you want!

This script comes in 2 flavors

NESTED BONE CONTROL.lua
The Global version of the script controls everything you assign beneath it. This will work for most occasions, but it might get a little troublesome if you have a switch layer with a bunch of bones. This script could crash your program if you try to control something like 20 smart bones in a switch layer all at the same time, so I created a switch sensitive version as well.

NESTED BONE CONTROL SWITCH.lua
The Switch Sensitive version of this script only moves the bones in a switch layer that is currently active, essentially ignoring all the inactive bones.

3. Add parent bone

Click on the parent bone layer and add a bone.
Give this bone the same name as the bone that you wish to control. (eg. hand)
Go to any frame other than frame 0 and animate the parent bone. You should find the child bone now moves too.
