I making a simulation and I need to count particles in a area, for example I set a cube trigger and calculate how much particle inside in this cube.
Is this possible on Obi ,and if it does, how can I do that

Yes, just use collision callbacks to count the amount of particles inside a trigger collider. See:

Let me know if you need further help,

Kind regards

Best regards

Kind regards,
