Modded car - invisible mirrors

[Trava]

Alright so I made a custom car for my own use and after importing it to the game and fixing some minor issues in 3dsimed I hit a brick wall.
No matter the settings, this happens: http://i.imgur.com/W8XIVPm.jpg http://i.imgur.com/3UOk0kj.jpg

Outside camera is fine, from the inside both left and right pane remove everything behind it.
Material is the same on every glass. Even when I set the side one to not render it becomes invisible from outside yet nothing changes from inside. Any ideas?

Looks like your interior window glass is not set to transparent correctly - you need to select the actual object and put isTransparent to true in the object properties.

Fired up 3DS max and found out that the actual window was not where I thought it was. For some weird reason it was set to Opaque. Thanks!
