Are you using texture with alpha channel ?

i havnt added any textures to my model yet.
K Airwolf, hope this will help you and all others that do not know how to add transparency.
You create a window with transparent and non-transparent areas with textures that contain an alpha channel.
In this case you need TGA files (which can contain an alpha channel, 32 bit) which can be converted into PAA files later.
Usually a picture for use on monitors has three color layers. Red, green, and blue (RGB, 24 bit). An alpha channel is something like a new layer, that can contain black, white, and all grey gradiences (?) (RGB + alpha = 32 bit).
Everything you mark as black in the alpha channel will be transparent. White will be non-transparent. 50% grey would be 50% transparent.
I've added three pictures to explain:
3D view, not rendered. Doors and windows appear to be non-transparent:
The texture I've aplied onto the pilots door. It contains three color- and one alpha channel:
3D view, rendered. Doors and windows with transparency:
Hope this helps you and anybody else.

PSC: That XYZ looks familiar.. You a fellow Maya user? If so, have you had any luck exporting to O2?
I can export in Obj, and convert to 3ds with 3Dwin4, but when I import to O2, it says there are no objects in scene.
Just a little bit worried http://www.flashpoint1985.com/ikonboard301/iB_html/non-cgi/emoticons/smile.gif
I'm sorry Konyak-2. I'm not one of these fellow Maya users. I've created my stuff using Cinema 4D. But a few days ago I got Maya, and now I try to make myself a bit comfortable with the user-interface of that programm.
But your import problem could have something to do with 4-point-polygons. With Maya you can create them. But 3D Studio Max does not support them (only 3-point-polys). Maybe the *.3ds format (I know, *.3ds is not the 3ds max format, its *.max) does not support 4-p-polys as well?

No that's not it. I have imported 4 sided polys from LightWave into O2 without problems.
