I'm finding that as I build scenes and test them it is often tricky to press UI Buttons because objects or body parts are blocking them when previously they didn't. Especially in intimate close up scenes it becomes a bit of a chore to get the angle right to hit buttons. I understand the reasoning for having objects block UI interractions but they are mostly edge cases that can be easily fixed by the scene designer, it seems to me it is more trouble than it is worth.
