Moving spotlight, Blurr?

[TheMasterRules]

For your sniper scope, perhaps this tutorial can help? https://www.frictionalgames.com/forum/thread-22215.html

As difficult as the language is and despite Lange's ban, it's not too bad a tutorial which may be able to assist you.
that reminds me, I should lock that thread...

I can help here.
Lange is gone, i can take over his stuff
So, if you need any help, be free to ask it to me.

Maybe we can unban Lange?

Anyways, there are ways to act like these.

You can also download some Full Conversion mods which use those Sanity Events.

Try study them, then after we are here to try and help you!

Edit;
Enigma has Day\Night sequences in the Forest(map)
As well has the mod BitterWood peak (if i remember correctly)

Go check those out and look for how they are scripted the events.
