About this Mod

Note This banner

Seamless Shaders adds a quick way to switch Iris shaders in game without needing to open the shader screen.

Simply press < to go backwards in your shader list and > to go forward. The mod tells you what shaders you are currently using when you switch, and has customisable keybinds so you're not restricted to the arrow keys.

Frequently Asked Questions

Does Seamless Shaders need to be installed on the Minecraft server?

No. Modrinth marks Seamless Shaders as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Seamless Shaders require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10, 1.21.9. Files for different loaders are not interchangeable.

Seamless Shaders is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
