I am having trouble with the scene lighting when I export to 3ws. These are the symptoms:
-The scene is quite dark, even at noon
-Only the side facing the sun is really lit; there doesn't appear to be any ambient illuminance.
-When I turn shadows on, it gets even darker and the buildings cast really long shadows and many of the shadows look incorrect
In previous versions of my model that I exported, the scene lighting is fine (it is nice and bright and the shadows cast correctly). As far as I know, the scene light settings are the same, with the same coordinate system, and time zone, etc.
Yes, they were made in the same version.
I have restarted and re-exported many times without luck.
Also, when the 'Sun position source' in CityEngine is set to 'Time and Month', the lighting/shadows seem fine within CityEngine. But the WebScene still has issues when the model is exported.
See attached imgs of shadows on vs. shadows off. The time is 12:30pm, the month is June.
Where in the world is your model? Try using the UTM zone - look up here..... NGA: (U) The Universal Grid System (UNCLASSIFIED)
If the coord system is explicit in the data ArcMap will pick it up if you drop the data in there (indeed CE should too).
If the data is in WGS84-LatLong I don't think it's supported by CE, you'll need to reproject into a system with metres as the base unit.
I would've though the default 'raw metres' system in CE should give sensible lighting for most models.
Maybe you are using 'head light' instead of 'scene light' in CE? Did you try and toggle the light type with 'l' (lower case L) ?

I was able to fix the issue by correcting the coordinate system.
Though, that is interesting about the lower case L vs. upper case and is useful information for the future! Thanks all!
