I am on PC, not steamdeck, just FYI. Also, if it helps to know I simply subscribed to the mod and enabled it in-game and that was it. Maybe I am doing something wrong, such as needing to put images in a folder first?

I am getting two errors.

FIRST ERROR:

Or multiply is not defind for null that's right!
I've no idea why does your MainScreenState.getInstance().lightningDelta return null but I'll add check to prevent errors

Framework could just work by itself (vanilla backgrounds fullhd or ultrawide) + optional direct images

You can fix the issue then? :)

Sure, will roll out with logo drop menu )

I guess that your error could be because of mods you use manipulate MainScreenState
But I'll fix the error...

Hm. Strange, because I had no other mods enabled.

Resub to get an update

Should be fixed.
Report if there any other errors

It works now! Thank you very much.

Does lightning work for you?

May be that's an option that prevents flashing lights? :P

Lightning does not work. I tried it with the example mod and the Girl mod, but neither work.

How may we add custom logos as well?

Looks like your MainScreenState.getInstance().lightningDelta does not exist... no idea why...

Might be linux?

We have to read lightning from java instance variables, because there is no any indicators in lua
But your game build can't access MainScreenState.getInstance().lightningDelta
Why? I've no idea... my build can do (screenshots captured it)
