I need to create great effects based on day time. How can I change light parameters based on hours in the new sky system?
the new sky system doesn’t do any of that for you just like the old system never did any of that for you.
you have to code your own thing.
If you know nothing about the obliquity of the ecliptic, I would suggest you start from there. Do research and understand what it is you are actually trying to do.
From then on, your ask is trivial.
You just change the settings based on the azimuth or whatever other value you wish to utilize to drive changes.
As of a few versions ago, there is an official plugin that sets the sun position accurately without you even having to do the math - however, if you do not understand the theory working with it is not very feasible.
And. It probably adds a rough layer of complexity compared to your own customized implementation, since you can localize the whole thing and save on mathematical computations that would otherwise have to be run every tick.
Yes this is what I’m saying. Since the version 4.25 I read there is a way to animate sun parameters but how can I do that exactly?
Via Blueprint? And how?
SkyAtmosphereLightDirection passes back the vector of the sun (directional light used in place of sun). You can do math from there: https://docs.unrealengine.com/en-US/Engine/Actors/FogEffects//Reference/index.html
thanks, but how can I automate them in Blueprint? And animate them as well?
