Hi Tero,

  If you are using the D3D version of Java3D, currently
there is a bug

4415723 - D3D: SPHERE_MAP TexCoordGeneration is incorrect

OGL version should work fine.

For the other problem:

"The EYE_LINEAR mode seems to behave differently if you have more than one
 TextureUnitState in your Appearance"

Can you please send us a test case for investigation ?

Thanks

- Kelvin
