View doesn't exist in OSG 1.2, but the SceneView that osgProducer wraps up does have the Light you want to control. It'll be rather than less logical and straight forward to access than it is with OSG 2.x though.

Hi Robert, thanks for coming back to me. One thing I left out of my mail was that I'm still using OSG 1.2 - though looking to migrate very soon. Is your response still valid for OSG 1.2?

Re: [osg-users] Seeking help in understanding HEADLIGHT light...
Hi Neil, The Viewer has a default Light, setup so that it's an infinite light coming from behind the eye point. The methods for controlling the Viewers light can be found in osg::View, so have a look at include/osg/View. Please note that you can switch off this default light, and adjust its settings as well.

[osg-users] Seeking help in understanding HEADLIGHT light...
Hi All, I'm trying to adjust the light that is created as part of the HEADLIGHT option, as it appears to be washing out an another light that I have in my scene. Essentially I'd like to take its effect down so that it only comes into play when I'm close to an object. I've tried adjusting the light on the scenedecorator, and I'm monitoring the apply function on the Light, and I see my values coming through, but I'm also getting the original values coming through. Its as if I have two lights in the room, but I haven't added any, other than the headlight option. In an attempt to track what was happening I've "discovered" that when the camera is set up, it also has a light created. I don't know if this is important or not. Can anyone help please ? Many thanks Neil ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
