Does Empire Minecraft have any restrictions on the use of Shaders? i want to know if there is risk of getting banned from the server when using shader packs, personally i dont like playing with the default graphics. I'm using this shader I don't know if I have a problem using it: https://minecraftshader.com/kuda-shaders/
As Joy_the_Miner said, EMC allows the use of all shaders. For a complete list of approved mods (including shaders) see the Approved Mods page. For shaders, specifically, scroll down to Aesthetic Changes.
