movement vision mod
there is only one downloadable version of mod so
its an issue i was having from the start to now
i had installed a lot of mods but even without them the issue occured ( i deleted all of them and left only movement vision and needed files )
the issue is that no matter the settings its always just dark and never shows any motion - as i typed earlier even deleting all other mods didnt help

What are your config values set to? Are you using any shaderpacks or resourcepacks?
