[osg-users] disabled lighting after migration

[Robert Osfield]

Hi Sebastian,

It's not possible to determine what is wrong from the details given.
The best I can do is provide some general pointers.

What can happen when upgrading is that more recent version contain
fixes/tighten up ambiguities such that things that worked by fluke in
older releases now behave differently because the OSG is now doing
exactly what the scene graph is telling it to do.

Another possibility to look is what is happening in any custom code
you have - could it be leaking state?

Robert.
