Oops. We forgot to include the following in the release notes for
1.1.2 release.
We discovered a bug in texture mapping whereby the wrong default value
was being used for texture mode if no texture attributes object was
being used. If a textured object was rendered with a null texture
attributes object in the appearance, then MODULATE was being used
rather than REPLACE, which is the specified default value. If a
TextureAttributes object was created using the default no-argument
constructor, then the correct default of REPLACE was used. We fixed
this bug in 1.1.2 and fixed all of our test programs that were relying
on the bug to explicitly create a texture attributes object and set the
texture mode to MODULATE. For example, the following code was added to
the TextureImage.java class in demo/java3d/TextureTest:
Texture tex = new TextureLoader(args[0], this).getTexture();
app.setTexture(tex);
>>> TextureAttributes texAttr = new TextureAttributes();
>>> texAttr.setTextureMode(TextureAttributes.MODULATE);
>>> app.setTextureAttributes(texAttr);
We apologize for any inconvenience that this has caused, and especially
for not including this in the release notes.

>In both cases, Im experiencing the same new problem:
>Whenever I have a textured object (with a default Material set to enable
