Question:

Decal groups seme to have an artifact that I can't seem to get around.  If I
am alpha blending between terrain layers java3d is still rendering the the
alpha blended layers in the transparency pass at the end of the rendering
cycle, even if these layers are in a decal group.  First of all, is there
any way to force these to be blended in multiple passes in the solid
rendering portion?  The problem is that since it is done after all solids it
contends with other alpha blended shapes in some instances.  Since it is
coplanar with the terrain there is no reason it should do this.

So

decal group (coplanar, same geometry array)
    - solid shape
    - alpha blend
    - alpha blend

If I am missing some option please let me know.

Secondly, would it be possible to pile them all into texture units within
the same shape and then use combine (somehow) to achieve the same effect?

Thanks!
