Here's how to get shaders in Minecraft 1.20 snapshots like 23w18a and so on!
1.20 is going to be a beautiful update!
*NOTE: this is how to get them within hours after a new snapshot. In the future for non-snapshots just use curseforge or modrinth for download.
The newest version of Fabric may or may not be needed, then Iris will have to make a change and drop their latest beta in Discord, they'll include their copy of Sodium too.
Just use the newest copy of your shaders, they aren't version specific. I copy all shaders over from previous instance.
Typically they have it ready in 6-12 hours after snapshot is announced by Mojang, sometimes faster.
I use MultiMC multimc.org to add Fabric fabricmc.net
(Get java if needed jdk.java.net/19/)
Iris Shaders (Discord link here)
modrinth.com/mod/iris/versions
Sodium
modrinth.com/mod/sodium
Get your favorite shader!
curseforge.com/minecraft/customization/complementary-reimagined
(The only shaders not working for me rain in the old Complementary)
(Even old SEUS shaders and BSL shaders work!)
Consider subscribing if this helped you! YouTube really doesn't like it when i keep it short for you, but I refuse to waste your time. I invent redstone and show off protips here, and always have a lot of neat stuff coming soon.

![Minecraft Infinite Sculk! 1.19 Snapshot 22w17a Experiments
In Snapshot 22w17a we got horns! Wardens do less damage, and sculk has less blast resistance. Wool stops allays from note blocks.
Iris for Fabric: (see their discord)
https://modrinth.com/mod/iris
(See my video on installing Fabric(+Carpet) if you need it)
I use Complentary Shaders
https://www.curseforge.com/minecraft/customization/complementary-shaders
Sculk landscaping:
1
summon minecraft:zombie ~1 ~ ~1 {Tags:[catalyst],Health:1,Silent:1b,ActiveEffects:[{Id:14,Amplifier:0,Duration:2147483647}]}
2
spreadplayers ~ ~ 1 50 false @e[tag=catalyst,type=zombie]
3
execute as @e[type=zombie,tag=catalyst] at @s run fill ~-1 ~-1 ~-1 ~1 ~-1 ~1 minecraft:sculk replace minecraft:grass_block
4
execute as @e[type=zombie,tag=catalyst] at @s run setblock ~ ~-1 ~ minecraft:sculk_catalyst
And later to remove all the catalysts:
execute as @e[type=zombie,tag=catalyst] at @s run fill ~-5 ~-3 ~-5 ~5 ~3 ~5 minecraft:sculk replace minecraft:sculk_catalyst
Permanent charge pool:
/data merge block ~ ~-1 ~ {cursors:[{charge:1,pos:[I; -259, 71, 412],decay_delay:10000,update_delay:0,facings:[down]}]}
