Collision between two Triangle meshs collider or two convext hall colliders not detected

@lbenhorin this is great for scattering a group of prims and avoid them colliding with each other. But if I understand correctly, the prims can still collide with other meshes in my stage such as the robot and trees/walls. am I wrong?

by the way i’ve made great progress with some amazing help:

I believe this is the right approach to detecting triggered collisions (given that they cannot be detected with good’old triggered colliders).

Thank you again for you help
