From 1.5 to 1.4.

As this won't make much difference to the look in implementations that ignore the adjacent IORs of the film.

But for those that take it into account, this will make the film visible rather than invisible by default (since specular_ior is 1.5 by default, and coat_ior 1.6).

Thank you for this fix.

Since MaterialX also depends on the thin-film IOR in rendering, we should make sure this change is reflected in the MaterialX reference implementation as well.
