Modpack Version

10-2.18

What happened?

When enabling the included shaders, the shaders do not display on screen. The lighting does change very slightly, but the shadows/water/texturing is unchanged from Vanilla minecraft and looks very similar to when shaders are disabled. Happens with both included shaders. Have restarted pack, have enabled, disabled, and re-enabled shaders, tried both packs, tried enabling and disabling both through hotkey and menu.

If you mean Euphoria Patches, that's known.
Cursefore "deletes old files" when updating, to remove old config files of removed mods. Meaning that it also removes the Euphoria Patches (EP) files... That happened because ATM team included the EP folder in the modpack directly before 2.18, if you see 2.18 log (fresh install) it actually generates the pack.
ATM team did a small oopsie of including the shaderpack directly before. And now they don't which is intended but because of how updating modpacks works this issue is created.
I (Euphoria Patches dev) have now implemented a detection system to detect if files have been removed so with the next EP update, updating ATM from before 2.18 to after 2.18 should cause no issues anymore. Though idk when I will release that version. Until then, people will have to manually get EP

I don't know what Euphoria Patches is, sorry :(

All I know is that up to version 17, the shaders were working and in patch 18 they're not - the "shaderpacks" folder still has two shaders in it (ComplementeryReimagined and ComplementeryUnbound) but they don't have any "options" in game

Do I just redownload the shaders and put them back in the "shaderpacks" folder?

The normal Complementary versions should work just fine.
If you look at it, it says Complementary + Euphoria Patches. Euphoria Patches being my add-on for it.
And to fix it, you delete the Euphoria Patches folders in the shaderpacks folder and restart the game

Ah thank you! Fixed :)
