you are using a blend function that is rendering order dependent (which
usually gives the best results ;) ). So, for correct transparency you
would have to render from back to front on the polygon level. OpenSG
does perform depth sorting for transparent objects, but only on the
object (Geometry) level.
You can try to use a blend function that is independent of the
destination color and see if the results are good enough for you.
Hope it helps,
Carsten
