Info
Shaders Utils is a plugin that allows you to apply a custom shader or a minecraft shader in minecraft, the plugin currently adds 12 new procedures to MCreator. It's simple to apply a shader, just select from the procedures menu the procedure called "Load shader with on player tick trigger" if you want to apply one shader, if you want to apply more select the procedure "Load multiple shader with on player tick trigger" and remember to set the trigger to "on player tick update". The procedures for applying the shaders are particular, they work with certain controls so I recommend that you always use the template and don't report a bug if Minecraft crashes with a procedure created without using the template. Others information: Shaders must be triggered by either player or procedure ticks and shaders must be activated and deactivated in the same procedure to work properly, from what i know. Since Minecraft 1.21 the shaders have changed, if you had created your own custom shader it is likely that you will have to adapt it for this new version. This plugin has all the procedures that work only on the client side, so make sure you check that you are on that side.
Vanilla path examples:
Minecraft 1.20.1: minecraft:shaders/post/creeper.json
Minecraft 1.21.1: minecraft:creeper
Minecraft Shaders List: here
Example (you can find this procedure in the procedure templates):
This procedure shows how to apply a shader of your choice via a condition that you place yourself ("your condition" is a place holder). The folder where I recommend saving your custom shaders is mod_id:shaders/your_shader.json. To create and put files in this folder you must create it by hand or via MCreator (if you know how to do it) or otherwise go to the workspace files (when you have opened your mod with MCreator select the Workspace bar and click on "open workspace folder") then go to src -> main -> resources -> assets -> mod_id -> and here you can make your folder and paste your shader. You can also apply a shader that is already present in Minecraft (just see the list I mentioned above).
You can also load your shader like this

Other Explanations

This procedure allows you to apply an existing minecraft monster shader by selecting it one from this list: (creeper, enderman, spider).

This procedure allows you to temporarily deactivate/reactivate the shader (it can also be done in game by clicking the f4 key).

This procedure can tell you whether a shader is active or not.

This procedure allows you to change the size of the screen (useful for making very strange effects), it's reset by removing the shader.

Hey I have a serious problem and question.
I have created a shader and it works fine in single player.But in multiplayer instead of the player who should get the shader,the shader gets another player.I have tested this with only two players and do not know what will happen with more.I am sure that the procedure is done properly

Don’t worry! I got it figured out :)
