I've noticed the cars included with SD have nice glass; the outside is slightly tinted while from the driver's perspective (inside looking out) the glass seems perfectly clear.
Also, I've noticed that the cars I make have terrible glass; sometimes when it's tinted, the driver and other interior items become invisible or see-through when viewed from the outside. I've not been able to pin this down to any particular reason as my results seem random. Not to mention that from the driver's perspective, the view is tinted -- not clear. This is especially crappy when viewed from the "bonnet" position when one might have a half tinted/half clear view as the viewing position might be partly sticking through the windshield.
Any solutions?
