It would be nice to bring back the previous braindance flashy lights, as an option, for those of us that don't suffer from epilepsy. It was very nicely made and trippy :D
The new soft lights are so underwhelming :/

Or at least i hope there'll be a mod that will do it

Created a thread over in the official Suggestions subform in regards to that:

Feel free to give it a red point and/or leave another comment.

SO I'm an archivist and have the original files... i'll do my best to find it and if we get mod tools make a repack tool update for it. It'll be on Nexus Mods as well, they already have a boatload there... im working on unpacking the archives but i dont have much time... hopefully someone with more time will make tools for us modd makers soon.

Once the 2077 engine is ported into Wither 3 (yes thats happening) it will only be a matter of time!
