We haven't seen this problem with our multi-monitor and cave configurations. The only thing in the view model that should be relevant is the default infinite eye specular computation, which you've covered by enabling local eye lighting. The view direction for each screen is determined by the orientation of that screen, but the view direction shouldn't affect diffuse lighting. Please send us a test program for investigation. If you can supply images that display the lighting discontinuity you're seeing that would be helpful too. Other things you might want to check are the relative brightness and gamma of the two screens; specular highlights have high shading gradients that can change their appearance quite a lot depending upon gamma and brightness. -- Mark Hood =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
