Cozy & Light is a vanilla-like shader pack for Java that runs on Iris. It adds better lighting and improved water, and its stated aim is to keep frame rates level with vanilla instead of chasing laggy realism. It is Java-only, so Bedrock players cannot run it.
Shader loaders and versions
- Iris: Minecraft 1.19 to 26.1.2.
What it changes
The pack favours atmosphere over spectacle. Its page describes better lighting, improved water and a few unnamed extras, all kept close to the vanilla look. CurseForge summarises it as a lightweight shader pack designed for a little comfort in vanilla.
How to install Cozy & Light with Iris
- 1.Install Iris, which enables shader packs on Java.
- 2.Open Video Settings and choose Shader Packs.
- 3.Use the button in that menu to open the shaderpacks folder.
- 4.Place the .zip file in the folder. Do not unzip it.
- 5.Return to the menu and select Cozy & Light from the list.
If the pack does not appear in the list, work through fixing shaders that will not load. The pack lists no other dependency.
Trade-offs
The pack ships a single release, 1.0, dated November 2025, and Iris is its only listed loader, so OptiFine users have no documented route. The frame rate claim is the creator's goal, not a measured result, and it will vary with hardware. The feature set is narrow by design. Players who want a different vanilla-like look can compare Aerial.
Questions about Cozy & Light.
4 questions
How do I install Cozy & Light?
Install Iris first, then open Video Settings and the Shader Packs menu. Use the button there to open the shaderpacks folder, drop in the .zip without unzipping it, and select Cozy & Light from the list. The pack needs no other dependency according to its file listing.
Does Cozy & Light work with OptiFine?
The file listing names Iris as the only loader, and the creator's instructions tell players to install Iris. OptiFine is not listed for this pack, so Iris is the route to use. Nothing in the listing promises OptiFine support, and trying it is outside what the creator documents.
Will Cozy & Light lower my frame rate?
The creator describes it as a lightweight pack that aims to keep the same frame rate as vanilla while improving lighting and water. That is a design goal rather than a measured promise, and real results depend on your hardware and the other mods you run alongside Iris.
Does Cozy & Light work on Bedrock?
No. It is a Java pack and depends on Iris, a Java mod that Bedrock cannot run. Bedrock players need a shader or texture pack made for that platform.
