Hi guys, this is not strictly related to three.js but to three.proton library a particle engine for three.js, maybe some of you have used it.
I am trying to use a MeshZone as CrossZone for the emitter, basically the goal is to have the particles destroyed as soon as they go outside of the MeshZone (defined through a threejs geometry).
My current attempt does not work, the particles are not destroyed even if when they are outside the mesh.
This is the live plunker: https://plnkr.co/edit/6y0xLCaFxSL176J6GQ9R
Hope you guys have some hint!
