    Hello there,
    I recently discovered a small problem while experimenting with terrain GPU instancing. I noticed that when I enable it, the geometry of the terrain changes very slightly. I have a camera that detects collisions via raycasting, however, when raycasting against the GPU instanced terrain the results seem to be inaccurate. Almost as if the collider is actually using the geometry that would normally be created on the CPU. Is this expected behavior or a bug?
