Each light must have a separate number in order to work. Having the same light parameters is not important: you won't be able to "factorize" the lighting. However in OSG, you are limited to 8 lights per RenderStage. To have 100 lights, you need to use multiple RenderStages. Else you can have only the most important ligths switched on (ie. the light sources in the current room). And to do my "advertising", you can use already existing code, such as the LightSourceManager from PVLE ( http://pvle.sourceforge.net/ - GPL'd ) which does 3/4 of the job. http://pvle.sourceforge.net/Doc/Html/classLightSourceManager.html But, as Gordon said, remember that more valuable information can be found in previous posts.
