Kerria

by decce6

Kerria speeds up how animated textures are uploaded to the texture atlas on the client, so the game spends less time on each update.

What it does

Animated textures in vanilla Minecraft are updated with glTexSubImage2D, a slow call that copies data from the CPU to the GPU and can cause a pipeline stall. Kerria replaces that step with two optimizations that reduce the cost of animated textures, and both run without changing how the textures look.

The mod is client-side only, so only the player's game needs it and servers run without it. Its settings can be changed on the video settings screen that Embeddium provides. Kerria is open source under the GNU Lesser General Public License v3.0 only, and its files are published for Fabric, Forge and NeoForge across 15 release versions, 1.16.5 – 1.21.1.

Kerria is a separate optimization from the animated-texture skipping in Embeddium, which skips uploads of animated textures that are not visible. Kerria instead makes the uploads themselves faster.

Key features

  1. Fast texture upload

    Textures are uploaded through persistently mapped buffers and pixel buffer objects, which reduces the cost of each atlas update.

  2. Animated texture optimization

    Animated textures are updated with a faster path than the vanilla glTexSubImage2D call, cutting the time spent on each frame of animation.

  3. Video settings integration

    Optimization options appear on the video settings screen provided by Embeddium, so players can adjust them in the game menu.

Use cases

Packs with many animated textures

Resource packs and mods that add many animated blocks or items put more load on the texture upload path, which is where Kerria works.

Who it’s for: Players who run a modded client with many animated textures and want to reduce the cost of those updates. Servers do not need the mod.

How it compares

Full comparison

Embeddium is client-side only and open source under the GNU Lesser General Public License v3.0 only, with files for 1.16.5 – 1.21.4. It skips uploading invisible animated textures instead of speeding up the upload, so it can be used alongside Kerria. Optimized Block Entities [OBE] is client-side only, open source under the GNU Lesser General Public License v3.0 or later, and covers 1.20 – 26.3 on Fabric, Forge, NeoForge and Quilt.

Questions

Which loader does Kerria support?

Kerria is published for Fabric, Forge and NeoForge. The latest Fabric and NeoForge files target 1.21.1, and the latest Forge file targets 1.20.1.

Does Kerria need to be installed on a server?

No. Players add it to their own game, and a server needs no copy.

How is Kerria different from Embeddium's animated texture option?

Embeddium skips uploading animated textures that are invisible. Kerria makes the upload of animated textures faster, and the two can be used together.

What the author says

Kerria is a mod that optimizes texture animations. In vanilla Minecraft, texture animations are handled rather inefficiently. Each time a texture is updated, it is uploaded onto the atlas via the slow glTexSubImage2D, which involves CPU->GPU upload and may potentially incur a pipeline stall.
