multiple compartments simulation

Do exist any way to interact between two objects on different compartments ?
I wanna to run my application with different simulation speed for some objects in only one scene . How can do it ?

Can you elaborate more about the different simulation speeds and interactions between different objects from different compartments?

You can put things in different compartments/scenes and simulate differently but in order to interact, you would either need to clone or move them into a common scene.

Hi HaiLocLu
I am going to write a program which exist many objects(NxActor) in it and i wanna to simulate some of these objects with a delta time and simulate other objects with a different delta time but i want all objects in the scene be interact with each other too .
thank .
