Help How to setup collision matrix for obi colliders?

[erdoganhuse]

Hi,

I see. You can't achieve this with phases, and we can't use a full collision matrix for particles. Unlike with regular rigidbodies, it is not uncommon in Obi to have tens of thousands of contacts per frame. Filtering them using a collision matrix could get really expensive.

Can you provide more details about your use case? There might be alternative ways to achieve what you want.

Of course. I have 4 pipe like objects in my scene and some of them overlaps with each other. At the top of each pipe there is a fluid emitter and couple of them emits fluid at the same time, because of that emitted fluids that belongs to specific pipe, also collides with overlapping pipes. I want emitted fluid to collide with just one pipe.

Actually changing collision logic for phase will be sufficient. If objects with same phase value collides with each other, my problem will be solved.
