Hi Juan,

It sounds like the ac3d loader hasn't placed your canopy in the
transparent bin. I'm not the author of this loader, nor a user of
ac3d so I can't really help on the low level details. You'll need to
look at the ac3d plugin to see if there if what is going on w.r.t
binning your data, or if you want others to ptich in a help solve the
problem you'll need to provide an example dataset that illustrates the
problem.

Please note that the OSG the order in the scene graph makes no
difference to rendering order as state sorting and bin assignment will
dictate the rendering order. This means if you want a specific
rendering order you'll need to use bins to order them.

Robert.

Hi,

I am doing an aircraft 3d model, using the Ac3d modeller, and I am having
problems with the transparent canopy in OSG.
In Ac3d, the canopy is transparent and you can see the cockpit inside. This
is achieved by puting the tranparent cockpit last in the object hierarchy.
However, when I use osgviewer to load the ac3d model, some of the cockpit
elements (pilot, seat, etc..) dissapear and reappear when you move the
camera.
Has anybody had this problem before? anybody know how to solve this problem?
thanks very much

Juan
