Very much so. I’ve got semi transparent (animated) curtains hit by sunlight i’m rendering right now… trace reflections on nearly doubles my render time and it’s near impossible to tell the difference. there’s a slight difference when you flick between them - but you cant tell why. The specular highlight is essential to the look of them though.
