Help Collision marked as Trigger not collides

[mmortall]

Obi Plugin v.3.5, Unity 2017.4.5f1 LTS
Collision marked as Trigger does not collide with cloth during simulation.
I've added a temporal fix in Oci.cs in two Set functions, see coding example below.

Is there a reason for it and can I turned simulation on also for trigger objects? Thanks.

ps. Also turning on/off isTrugger not makes collider dirty for Obi, so you need to disable and re-enable it for making them counted by Solver. 

Code:

        public void Set(UnityEngine.Collider source, int phase, float thickness){
            boundsMin = source.bounds.min - Vector3.one*(thickness + source.contactOffset);
            boundsMax = source.bounds.max + Vector3.one*(thickness + source.contactOffset);
            translation = source.transform.position;
            rotation = source.transform.rotation;
            scale = source.transform.lossyScale;
            contactOffset = thickness;
            this.collisionGroup = phase;

           //for some reason trigger colliders are not taking part in the simulation
           this.trigger = false;// source.isTrigger;
            this.id = source.GetInstanceID();
        }

Triggers are just that, triggers. By definition, they do not generate collisions and won't take part in the simulation at all. See:

https://unity3d.com/es/learn/tutorials/t...s-triggers

Also, excerpt from the Unity manual:

A collider configured as a Trigger (using the Is Trigger property) does not behave as a solid object and will simply allow other colliders to pass through. When a collider enters its space, a trigger will call the OnTriggerEnter function on the trigger object’s scripts.

Thanks for clarifying.
