Summary	0003755: Multiple NoesisView event handling order
Description	When you have multiple NoesisView, event handling order of OnGUI (for hit test, mouse event handling, etc.) is not guaranteed/undetermined/random. This is especially troublesome when you implement on NoesisView for HUD and another NoesisView for World UI. I can workaround this issue by deactivating/activating cameras in the order I want. It seems camera depth is not helpful nor guarantees the execution order of OnGUI call. I think the user will expect the depth of the camera will manage hit testing, which is not.

Platform	Any

christallire 2024-10-28 12:05 reporter ~0010072	Yes, I say the code on OnGUI callback - does not work. I guess it does not work because OnGUI call is ordered by either DefaultExecutionOrderAttribute or the order they are added to the event loop? I think I also saw someone fixed a similar thing in Unreal Engine :) (idk where exactly it was)
