Thanks Howiie.

Image A is the Tapui scene from the Wizard with your clouds/lights group brought in and scaled over the mountains.

Image B is with the Tapui main light set to off and the sun placed at the horizon.

Image C is as B with all your bulbs reduced down to 25%.(I note that all your bulbs are now reading a range 0f 400"?)

I gather, in starting from scratch, that scene lighting generally, bulb light strengths, and bulb light ranges may all play a part. Maybe some "rules" for these relationships are missing in my understanding,

The problems above are similar to my own, start from scratch experiments.

Thanks           Brian
