partial pass tru ?

Hi, there are some ways you can do this. Here's an implementation using hole punching to create a box at (0,0,0) that can act as partial pass through when passthrough is enabled:

Entity.create(
        Box(Vector3(-0.5f, 0f, -0.5f), Vector3(0.5f, 0.01f, 0.5f)),
        Mesh(Uri.parse("mesh://box")),
        Transform(),
        Material().apply {
          alphaMode = AlphaMode.HOLE_PUNCH.ordinal
          shader = SceneMaterial.HOLE_PUNCH_SHADER
        })

You can edit the size of the box and create a system that makes the box's transform always 2m below the player's head or something similar to achieve what you need. Hopefully this helps
