How do I turn on Cursed Descent Shaders?
It runs as a vanilla shader pack, so you enable it from the game's own pack menu (Options > Resource Packs) by moving it into the active list and clicking Done. If you have other packs that change visuals, place it at the top of the active list so it takes priority.
Do I need OptiFine or Iris to use Cursed Descent?
No. It works directly as a vanilla shader pack without heavy setup, so it doesn't rely on a separate shader loader. Running another shader system on top of it can cause conflicts, so turn those off if the effects look broken.
I turned it on but the game looks almost normal. Is it broken?
Probably not. The effects start mild and slowly escalate the longer you play. Keep playing for a while and watch for color warps, odd lighting and screen distortion creeping in.
Why does my screen keep getting weirder the longer I play?
That's the core mechanic. The visual glitches, color warping, light-level changes and screen geometry distortion build in intensity over time. A long session will look far more chaotic than the first few minutes.
Can I lower the intensity or stop the effects from escalating?
Escalation is the point of the pack, and there's no documented intensity slider. Your real controls are how long you play in one stretch and turning the pack off when it gets too much.
How do I turn Cursed Descent off in the middle of a game?
Open Options > Resource Packs, move it out of the active list, and click Done. The normal visuals come back without leaving your world. This is the quickest fix if the effects become unplayable or uncomfortable.
Is this safe if I get headaches or am sensitive to flashing?
Be careful. The pack deliberately uses rapid visual shifts and screen glitches, which can cause eye strain and may be a problem for photosensitive players. Take regular breaks, and if you feel discomfort, disable the pack immediately.
Does Cursed Descent change my world or gameplay, or just how it looks?
It only changes visuals: colors, lighting and screen geometry. Blocks, mobs and your world itself stay the same. The difficulty comes from not being able to see clearly, so turning it off returns everything to normal.
Does it work on multiplayer servers, and will my friends see the glitches?
It's a visual pack that runs on your own client, so the server doesn't need it. Other players won't see your effects unless they enable the pack themselves, which is a fun way to have everyone suffer together in a challenge run.
My FPS dropped or the effects look broken. What should I check?
Make sure it's the only shader effect active and sits at the top of your resource pack list, since other visual packs or shader loaders can clash with it. If performance is still rough, lower render distance and other graphics settings to free up headroom for the screen effects.
