Changing a 3d scene from daytime to nighttime?

[Veleno]

Hi John,

The lighting & shadows in the Piazza scene is baked into static maps, so it's not possible to relight it the way you're intending unless the lightmaps are removed. I checked the file in Inspector, and they're all on texture unit 1.

To get rid of them, you'd loop through all the objects in the scene with python and clear the texture unit. Jeff may be able to advise on that part.

Hi again John,
I exported a version with all the lightmaps stripped out with realtime shadows coming from a directional light instead.

You can get that here: piazza_20170509_nolightmaps.zip (34mb)

Feel free to play around with it as you like!
