Disclaimer: This may or may not be a bug in studio. The reason why I’m posting it here is because it won’t let me post a bug report.
I’m having this problem with the parts inside of another part(s).
What materials are used here? sometimes this bug occurs with multiple transparent objects also.
If you use glass for the bottle and put something with transparency inside it I think the thing turns invisible but I don’t know why you can see it at an angle.
If this is the case then don’t use glass for the bottle lol.
