Just an idea... to CoronaSun.
And environment map that mimics a night sky with stars and moon.
Actually one could select a place on globe and a date and generate some kind of exr texture to put in the environmental slot.
For shure there is plenty of places on the net where one could pick information for that.
Off course a slider to set the amount of stars and moon size. I've seen that maps on cell apps.
It would be a totally awesome add for Corona.
... or just add a greater than 90 degree slider to the corona sun model to mimic nigth sky.
Just my 2 pesos cuates...
