In many threads I've read here as well as in recent webinars it is recommended to use the Deforming Object shelf tool when setting up your DOP network in a FLIP sim. And then always turn off 'Use Deforming Geometry'
However in a simple FLIP sim I have with falling objects into a FLIP tank RBD Object is the only option that seems to work. If I use Deforming Object I can't get the gravity force to take effect.
Can anyone tell me in a nutshell what the advantage of Deforming over RBD Object shelf tool is, and how I might enable the gravity force when applying Deforming Object to any geometry?
