to me it Looks like the Basic sorting Problem.
translucent faces cannot be sorted properly with deferred shading like UE does.
You either have to stick with the “bottle in the back is rendered in front” or you can use Forward shading in 4.13
if your bottle in the front is completely opaque, use the Default lit shading model instead of translucent. this gets rid of the sorting issue.
renounce translucent shading model whenever possible!
