clothing opacity problems

is it possible for a character to wear two shirts each with their own transparency maps.
i am using an under shirt with a transparency map and an over shirt with a transparency map.
the problem i'm getting is that the over shirt becomes transparent where the under shirt is, if i make the undershirt completely transparent then the over shirt works fine.

is it possible to get both shirts transparency maps working with out conflicting each other?

Can you show an image of what you are seeing, and if possible the transparency maps you are using?

I assume this is a viewport issue more than a render issue? Generally speaking, transparent objects are drawn after the opaque ones in a scene and in many cases are not depth-checked against other transparent objects. What this means in layman's terms is that the order in which it draws each transparent pixel can get mixed up if they share the same screen space. The reason it's done this way is simply to speed up writing the pixels to the screen buffer, and thus keep everything running smooth.

In short, any time you have two transparent objects overlapping you may see this issue. That said, the 3Delight render engine takes all of this into consideration when rendering, and you can have multiple layers of transparency without it affecting the final result.

OK well i deleted the over shirt and made a new one making it the same way, and it works now.
no idea what was wrong though, the first picture shows what it was doing, and the second picture shows what it should have been doing.

the third pic is the undershirts transparency map and the final pic is the over shirts trans map.

it sounds like it might be what herald of fire has said, as when i did a render of the first pics it rendered correctly.

thanks:)
