Hi, I'm trying to put some basic lighting into a scene that's got lots of VRML objects in it. Each VRML model I'm loading is real simple (a lego brick, a cone, etc). As I understand, one has to generate normals to get lighting to work, and to do that, I need to use a NormalGenerator, which needs a GeometryInfo. But, I can't seem to get a GeometryInfo from a SceneGraph I load from VRML.
Has anyone loaded a VRML object and lighted it? How'd you do it?
Thanks in advance!

Chances are that your models already have normal information included.
To turn on lighting, you need to make sure you do two things:
-include lights in your scene graph. This can either be in the VRML or added to your scene graph later.
-Make sure you call setInfluencingBounds() on the light. Otherwise the ligth will not light up any objects.
