Help How detect amount of fluid in a container

[N0Skillz]

Hi,

Subscribe to contact callbacks to detect particles inside a trigger collider. See:
http://obi.virtualmethodstudio.com/tutor...sions.html

Hi there,

Since this awesome asset is new to me, I'm still learning its depth therefore I kindly ask you to bear with me as I'm just going to let my thoughts out...

Is there any option to subscribe only to a specific collision layer, i.e. "Bucket" ? - or is there any "collision matrix" like the Unity's "Layer Collision Matrix"? 
... as per the documentation under "Scripting Collisions" I'm receiving all the particle contacts/collisions and having to call :

Code:

foreach (Oni.Contact contact in currentContacts)
{
    Component coll;
    if (ObiCollider.idToCollider.TryGetValue(contact.other, out coll))
    {
        if (coll.gameObject.layer != 11) // Layer I want to check against
            continue;

        // ... Rest of the code ...
    }
}

And with 1000 particles I get approximately 10-15k iterations which seems a bit of overkill.

Am I missing something or this is the only way to do it?
