Re: MSPhysics plugin by Anton Synytsia
Can anyone help with ruby code or MSPhysics script to allow
1. turning layers on and off and/or
2. hiding and unhiding objects
while running an MSPhysics animation
I need to embed it into my existing MSPhysics animation script to turn things on and of in response to model conditions and keyboard events.
