Hi,
There are two bugs in earlier release of Java3D :
4391537 - Texture disappear if Canvas3D in JInternalFrame
is minimize and restore again
4395116 - Texture disappear when Canvas3D remove and add back to panel later
They are fixed in v1.2.1 beta2. Please give it a try.
If the problem is still there, please send us a test case
for investigation.
Thanks.

The same thing happens if you put Canvas3Ds inside of JInternal Frames. I
think it's the heavyweight vs lightweight issue. JPanels and JInternalFrames
are all lightweight, but Canvas3D is heavyweight. If you try to overlap the
Canvas3D with a lightweight component, you lose the texture. I think that's
happening with the problem with your JTabbedPane. Why it's happening I
couldn't tell you?
I don't know how one could fix the problem. There were those offscreen
rendering solutions which essentially made Canvas3D lightweight, but would
be a performance hit and are not absolutely trivial to implement.
My suggestion would be to avoid putting Canvas3Ds inside a JTabbedPane or a
JInternalFrame as well. If you are using multiple Canvas3Ds inside your
JTabbedPane consider implementing your own JTabbedPane which uses just one
Canvas3D but adds and removes elements to and from the scenegraph.
