[JAVA3D] TransparencyAttributes only works with SCREEN_DOOR

[Kevin J. Duling]

I'm having some trouble with this bit of code:             final float trans = 1.0f - material.getTransparency();           if (trans > 0.0f)           {             TransparencyAttributes transparency = new TransparencyAttributes();             transparency.setTransparency(trans);             transparency.setTransparencyMode(TransparencyAttributes.SCREEN_DOOR); // this is the only one that works??             app.setTransparencyAttributes(transparency);           } TransparencyAttributes allows several different settings for the transparency mode.  But the only one that seems to be working for me is SCREEN_DOOR.  If I choose NICEST, FASTEST, or BLENDED, the object completely disappears.
