Thanks for the response.
Heh I am so used to close to perfect "ports" it never occured to me that it
would not work on every target, even if it had to be done using an
inefficient method.

Detail texture is not support in D3D,
>From README
=====================================================
Information on the Direct3D Implementation of Java 3D
=====================================================
Unsupported Features
--------------------
The following features are currently unsupported in the Direct3D
implementation of Java 3D:
Line width
Line antialiasing
Point antialiasing
PolygonAttributes backFaceNormalFlip
RenderingAttributes ROP_XOR
Stereo
Texture features not support:
Texture color table
Base/Maximum Level
Max/Minimum LOD
LOD offset
Detail Texture
