I thought I knew what was going on, but now I know I don’t, hrmm…

The sphere farthest away in view is instance0, the nearest is instance9. Dispose instance1 and updated the gpu pick list, now the pick results are borked. Nearest is now instance8, instance2 is now instance9?
If you reverse the dispose and update order to
picker.setPickingList([...list]);
scene.getMeshByName("instance1").dispose();
You get a different result…hrm… Does anyone else see what I’m seeing?
