I used RayHandler.useDiffuseLight(true) and now my unlighted part of the screen is black no matter what ambient light value I set. Is this normal? I have seen other application made with libgdx which use both diffuse light and ambient light and it works fine... How do I get the ambient light to work with diffuse light? If I don't use diffuse light the quality of the textures is very poor as the light doesn't combine with the texture color.
