How to dim a layer at nightfall?
Posted: Mon Nov 28, 2022 11:02 pm
The title describes my issue. As the sun goes down i need less light output, and when the sun goes up again i need to go back to 100%.
So what i tried is
* draw a black rectangle "Nightfademask" over my visual.
* control its opacity with Weather->Time→Night position.
* When night starts (as Night Position goes from 0 to 0.1) i dim the mask from 0 to 20%
This works… partially.
Problem: after the night is over (Night Position jumps from 1 to 0 again while Day position begins to increase), my Opacity channel doesn't go back, it stays 20% which seems illogical to me.
Also, this would give me a nice slow fade after sunset, but it theoretically would jump back abruptly at sunrise.
So… this concept is flawed and it straight up doesn't seem to work for reasons i don't yet understand.
Please elucidate me: How would I do this properly? Can't we do a more complex mapping where, as night goes from 0…1 my opacity value can go from 0% to 20% and then back to 0%? Any way to use math expressions in control params perhaps?
