Re: [osg-users] Many light0 in the same scene ?

[Robert Osfield]

HI Kevin,

RIght now the way to do multiple lights is to use the OpenGL hardware
lights GL_LIGHT0... GL_LIGHT7, must this is limited just one entry per
light per RenderStage.  To scale up to more lights than 8 then you
have use tricks with multiple RenderStage.  This topics is rather
complex and has been discussed on osg-users alot previously so please
search the archives for info on it.

Robert.
