Hi Sebastian,

I've loaded your model and applied your change but get the same
result, a white/grey scene that isn't lit correctly.  By doing a
osgconv tester.flt test.osgt and then looking at the result I can see
that all the Light's share the same LightNum.  I would have expected
them the Light's to be number 0,1,2,3 and for these to be enabled.

How did you get the result you've provide in the Clipboard01.png?

Robert.
