Hi,
There is currently a bug :
4364572 D3D: Texture transform for translation or
combine with TexCoordGen did not work
which affect the functionality of Texture Transform.
For the memory leak bug, can you reproduce it using
OpenGL version of Java3D ? Please also try to run
in Emulation mode -Dj3d.d3ddevice=Emulation (I assume
you are using Java3d v1.2 beta1 for DirectX)
to see if this happen. What graphics card/OS are
you using ? Please give us a test program to
reproduce this problem.
Thanks.

>Hi Java3D Team:

>My code is:

> tempVec1.y += CLOUD_SPEED * interval;
> cloudTextureTrans.setTranslation(tempVec1);
>
> Flt.FltScene.skyTextureAtt.setTextureTransform(cloudTextureTrans);

>The above code gave me a WONDERFUL effect of 'Floating Clouds', But,

>10 Minutes and crashs the OS.
>
>I checked the API documents for setTextureTransform(), Doc say:
>===============================
>public void setTextureTransform( Transform3D transform )
>
> Sets the texture transform object used to transform texture
>coordinates. A copy of the specified Transform3D object is stored in this
>TextureAttributes object.
>===============================
>I am guessing the problem is in 'A copy of the specified Transform3D object

>By the way, when I run my App with MS DriectX, setTextureTransform() does
>not takes any effect, IE, nothing happen, This is another problem for
