I’m trying to use the AssignKey function in max script to copy a sequence of keys from place to another on the same Animation controller. I believe the method is to:
- use addnewkey at the new time position
- look up its index
- use assignKey to overwrite its value with the source key value.
Basically it doesn’t work 
Addnewkey works but assignKey just deletes keys the new keys I’ve created
Is this a bug ?
Has anyone got this to work ?
