I need to pour water in glass and than someone hit the glass of the table and it shatters. The problem is that falling from table is starting at first frame. How can i offset time when glass is filled with water. Im using on RBD object velocity to push it from the table

You can lock the “glass_mug” file node (Right Click>Flags>Lock/Unlock) That way it will be baked into the file so we can see it in the example you've posted.

As for your question depending on your setup you could simply change the “Start Time” parameter on your AutoDopNetwork to whatever frame you want the RBD sim to start.

You could also take your glass_mug RBD_Object dop and set creation frame to whichever frame you want.

In addition you can add a switch node to your DOP network and switch between a static and active object. I've attached a modified version of your file with an example of how that would work.
