Patterns on transparent parts: To BFC or not to BFC?

[Philippe Hurbain]

What I suggest is to NOCLIP the pattern portion, and only on parts that are usually transparent. Patterned parts have generally very specific colors, it is highly unlikely that the same pattern appears in opaque and trans parts. And if someone wants to use such a part as opaque, yes, there will be a tiny speed penalty, but I don't think it's that important.
