Problem when multiple transparency objects
Hello all,

Second post for a second problem ...

I've just created custom windows (double and single) with Blender and imported them in SW3D, from OBJ files.
The result seems good when displaying them isolated.

But when they "collide" (when one window is behind another), I have a strange display problem: some opaque parts become transparent.

You can see the problem with the following picture.

Another strange behaviour: it depends on the creation order.
In my example, there is no problem with the left and behind windows (which have been created BEFORE the front one), but there is a problem with the right window (created after) !?!

I checked the normals, textures, alpha, ... and all seem right !

Have you some ideas ?
Could it be a bug of Java3d or my graphic card or SW3D ?

A big thank you in advance.

Laurent.
