Hello

I already mentionned that a few weeks ago without any answers. It's because
as soon as you set a transparency attribute (with 0 as transparency value)
the
related geometry is drawn in a second pass using the z-buffer in read-only
mode.
That's way you are able to correctly draw a transparent sphere INSIDE
another
transparent sphere (which is not possible otherwize, i.e. using fully the
z-buffer).
If you do not want this feature, you can set :
view.setDepthBufferFreezeTransparent(false);
assuming view is a ... View.
This is really annoying when you want to make billboards whith partially
transparent texture AND objects inside transparent objects at the same time.
hope this help
