Help Particle passed through collider

[josemendez]

Hello there, I have made a ground attached with obi collider, and for some reason sometime there will be some part of the rope particle passed through the ground and the particle is blocked under the ground. Is there any way to solve/avoid this problem? thanks

This is known as tunneling and is common in all physics engines. Depends on what kind of collider you're using, its thickness, your rope resolution, your timestep, and multiple other things. Without a more detailed description all I can recommend is to use a ObiParticleRenderer on your rope to see what the particles are doing at runtime.
