Initially Overlapping Objects won't collide - Bullet

Hi,

I have two fractured boxes : A and B. Each box has independent glue constraints, i.e. no constraints between A and B pieces, and each has its own packed rbd DOP node.

1 ) If A and B are initially overlapping, the will fall together under gravity, i.e. Bullet won't separate them 

2 ) If A and B are initially separated and have initial opposite velocity, the collide

My question: What's the logic here? Is it like if objects are initially overlapping they won't collide

Thanks...

Okay, I found why: Basically the solver initially checks for overlaps, if found it sets found_overlap to prevent collision...

 

found_overlap Point Integer

When the solver sees an object for the first time, it checks whether that object is initially overlapping with any other objects in the simulation and prevents any such pairs of objects from being forced apart. This value is used by the solver to determine whether it has performed this process for the object on a previous frame.
