Moho Animation Forum

I have heard something about a tool for AS capable to copy and flip selected bones.
Where can I find it? I searched on the web but I found only an old post in a dead forum...

I know Vern has a tool to make that. I didn't tried myself, but check his thread on script section.

I found it, but it don't work!
When I try to copy a bone the only thing I can obtain is an LUA error Window.
