Well, I'm not asking how to change the switch and group indexes, I want to know how to check those on a characters boneset so I can know what to input for those indexes when I'm editing the model changers. Sorry if this is bothering you.

The event has two parameters:
- Switch Index
- Bone Group Index

I believe this is self explanatory:
Switch index is the index of the switch to select groups from.
Bone Group index is the index of the group of bones that you want visible.

Using the model changer will make only that group of bones visible. All other bone groups will be turned off.

I do not understand this part. How do I check the switch index and bone group index of the bones I want to make visible? Thanks in advance and sorry if this question sounds dumb.
