In J3d 1.3 beta 1: If you have an alpha blended object which is being sorted by the transparency (not in an ordered group), and that object has geometry which falls outside of view fustrum then the geometry will sometimes be clipped, and sometimes will be rendered without transparency. The bounds of the shape are ignored for this culling. It might not be culling, but could possibly be some sort of other corruption, but the result is that none of the geometry will be drawn, or the geometry will be drawn without blending, or the geometry will be drawn correctly. Our tree imposter system uses a single geometry array to draw all the trees in the background and this bug was causing eratic behavior. I have moved it out of the root scene and into the ordered groups to stop it from being transparency sorted, and this solved our problem.
