Please raise a bug so we can see how you have configured this scene.

I am getting a very similar error. Will attempt to create a formal test scene for bug submission tomorrow. Using 4.6.1p5.

I’m getting a similar error in 5.2.2f1, as mentioned in this thread. Was there a regression with regards to this?
