To get transparency to do anything there needs to be an active
BlendChunk. The SimpleMaterial creates one for you, but only if the
transparency is not 0.
So the best way to do this to either use a ChunkMaterial and explicitly
add the BlendChunk, or just set the Material's transparency to an
arbitrary value != 0, the geometry will override it.
Hope it helps
