ETF Mod gives every mob in your world its own look: random textures, glowing emissive eyes, blinking animations and player skin features. It reads OptiFine-format resource packs and runs on Fabric and NeoForge alongside Sodium and Iris.
Try what ETF does to a mob's face.
ETF Mod, full name Entity Texture Features, is a client-side mod that expands how Minecraft Java Edition draws mobs and other entities. Vanilla gives each mob one texture; ETF lets resource packs supply many, pick between them with rules, and add layers that glow, blink or react to the world.
Random and emissive mob textures were long exclusive to OptiFine. When the community moved to Fabric and performance mods like Sodium, those packs stopped working. Developer Traben released ETF to bring the features back on modern loaders, and later added Entity Model Features.
ETF exists so resource pack artists can build once in a familiar format and players can enjoy the result without giving up the rest of their mods. It focuses on rendering entities well and leaves performance and shaders to specialised mods.
Anyone playing Java Edition with resource packs: survival players who want varied mobs, builders who take screenshots, pack creators, server communities and modpack authors who want polished visuals without OptiFine.
"If you use Fabric or NeoForge and any texture pack beyond vanilla, ETF is the first mod we install. It is small, stable and unlocks most of what made OptiFine packs special."
ETF Mod editorial team, after testing on 1.20.1 and 1.21.1
Nine things ETF adds to Minecraft, and why they make your world feel more alive.
Give every cow, wolf or villager its own look. Packs can choose skins by biome, height, name, weather and more, so a herd never looks copy-pasted. How it works
Eyes, runes and markings glow at full brightness in the dark. Night scenes and caves gain atmosphere without a shader pack. How it works
Mobs blink on their own using optional blink textures, a small detail that makes the world feel alive. How it works
Add capes, transparency, glowing pixels and more to your own skin. Other ETF users see them in multiplayer. How it works
Packs can add custom enchanted overlays to entities for magic mobs and armor with personality. How it works
Reads OptiFine's random entity and emissive formats, so thousands of existing resource packs work without edits. How it works
Lightweight checks and caching keep frame rates steady, and it runs happily next to Sodium and Iris. How it works
Toggle each feature, change emissive rendering and enable debug output from a clear settings screen. How it works
Pair it with Entity Model Features to render custom models and animations such as Fresh Animations. How it works
ETF is tiny. If Minecraft Java Edition runs on your computer, ETF will too.

From your first resource pack to writing your own texture rules.
Four steps, about five minutes
Write your own texture rules
Write rules in .properties files to choose textures by biome, height, name, weather or health. Add _e layers for glow and _blink textures for blinking.

What happens between a mob spawning and you seeing its texture.
When an entity spawns or loads, ETF notes its type, position, biome, name and other properties.
ETF looks for a matching .properties file in your active resource packs.
The first rule that matches chooses a texture, using weights where set, and the choice is cached.
Emissive, blink and enchanted layers are drawn on top of the base texture.
Conditions such as health or name are re-checked so textures react to the world.

An honest look after testing ETF on several versions and loaders.
Make survival worlds feel less repetitive with varied herds, glowing cave mobs and blinking villagers.
Learn file formats, rule logic and pixel art by building a small resource pack and testing it live.
Test modpacks on Fabric and NeoForge knowing texture features will not conflict with performance mods.
Server networks and modpack studios ship consistent, polished visuals without asking players for OptiFine.
Use texture variants to tag entities visually in experiments, recordings and educational builds.
Capture striking night footage with emissive textures and give recurring mob characters named looks.

A short walkthrough of random textures, emissive layers and the settings screen. The video loads only when you press play, so the page stays fast.
Common errors and how to fix them fast.
Download the ETF build for your exact Minecraft version and loader, update EMF alongside it, and remove OptiFine. Read logs/latest.log and search for ERROR.
Enable the pack, move it to the top, confirm folder paths match vanilla exactly, and press F3 + T.
Make non-glowing pixels fully transparent in the _e file. With shaders, switch ETF's emissive rendering mode.
Some mods that replace entity rendering can override ETF on specific mobs. Check the GitHub issue tracker for your version before reporting.
Use Sodium, lower entity render distance, disable ETF features you do not use, and keep huge texture packs to what you actually need.

I run a 180-mod pack and ETF has never been the problem. Fresh Animations plus ETF made my farm feel alive; every sheep looks slightly different now.
The properties format is the same one I learned for OptiFine, so porting my packs took an afternoon. Debug output shows which rule matched, which saves a lot of guesswork.
Because it is client-side, I recommend it to players without touching the server. Fewer support tickets than when half the community used OptiFine.
Great way to learn how resource packs work. The only snag was matching versions between ETF and EMF the first time. After that it was smooth.
Emissive eyes at night look fantastic in recordings. With Iris I switched the emissive mode once and never touched it again.
Installed it with the Modrinth app in two clicks. I did not expect blinking villagers to make me smile this much.
Quick answers to the questions players ask most.
ETF Mod, short for Entity Texture Features, is a free client-side mod for Minecraft Java Edition created by Traben. It adds random mob textures, emissive glowing layers, blinking mobs and player skin features, reading the same resource pack format OptiFine uses, so packs built for OptiFine display correctly on Fabric and NeoForge.
Download it from the official Modrinth or CurseForge project pages, or from the developer's GitHub releases. These are the only sources the developer publishes to. Our download page links directly to them and includes a browser-based SHA-256 checker so you can confirm a file has not been changed before placing it in your mods folder.
Yes. ETF is free to download and use, and its source code is public on GitHub. There are no paid tiers, locked features or accounts. Be cautious of any site that asks for payment, a survey or a sign-up before downloading, because the official files are always free on Modrinth and CurseForge.
ETF has builds for Fabric and NeoForge on current versions, with Forge builds for many older versions. Quilt players can usually run the Fabric build. Support changes between Minecraft versions, so filter the official file list by your game version and loader before downloading instead of assuming a loader is covered.
No. ETF is written for Minecraft Java Edition and depends on Java mod loaders, which Bedrock does not have. Any file advertised as ETF for Bedrock, Pocket Edition or consoles is not made by the developer. Bedrock resource packs can imitate some effects through their own entity files, but results depend on each pack.
Check the dependency list on the version page you download, because requirements can change between releases. Most players install Fabric API anyway since many other mods need it. Mod Menu is recommended so you can open ETF's settings from the title screen, but it is optional and the mod works without it.
The official builds are open source, distributed through Modrinth and CurseForge, and scanned by those platforms. The mod only changes how textures render on your computer and does not need an account or collect personal data. Avoid reuploads on unknown sites, and compare the SHA-256 hash if you want extra confidence.
Yes. ETF is commonly included in modpacks, and the platforms handle permissions when packs reference the official project. Always link to the official download instead of rehosting the jar. Review the license in the project's GitHub repository if you plan to redistribute files outside Modrinth or CurseForge.
Delete the old ETF jar from your mods folder and add the new one for the same Minecraft version and loader. Update Entity Model Features at the same time if you use it. Your settings stay in the config folder. Launchers like Prism and Modrinth App can update mods automatically.
No. ETF is client-side only. It runs on your computer and changes how you see mobs, so you can join vanilla servers, realms and modded servers with it installed. Other players only see ETF effects if they also run the mod, which matters for player skin features and shared screenshots.
Check that the resource pack is enabled and placed above other packs, that its folders follow the exact vanilla texture paths, and that random or emissive textures are switched on in ETF's settings. Then press F3 + T to reload resources. A single misspelled folder name is the most common cause.
Most crashes come from a version mismatch, a wrong loader or OptiFine installed at the same time. Open latest.log in the logs folder, search for ERROR, and read the lines that follow. Download the ETF build for your exact Minecraft version and loader, update EMF alongside it, and remove OptiFine.
No. ETF is designed to replace OptiFine's entity features, and running both causes crashes or missing textures. For performance use Sodium, and for shaders use Iris. Together with ETF and EMF, this combination renders the same OptiFine-format resource packs while staying compatible with other Fabric and NeoForge mods.
Yes, through Iris on Fabric or NeoForge. Emissive textures can look weaker or stronger depending on the shader pack. ETF's settings include an emissive rendering mode, and switching it usually fixes the look. Some shader packs have their own emissive handling, so test both options and keep what looks best.
The impact is small for most players. ETF caches texture decisions and only re-checks conditions when needed. Very large texture packs with many variants use more video memory. If frame rates drop, pair ETF with Sodium, lower entity render distance, and turn off features you do not need in its settings.
ETF changes textures: variants, emissive glow, blinking and skin features. EMF, Entity Model Features, changes models, adding new shapes and animations from OptiFine-format .jem files. EMF requires ETF, but ETF works alone. Install both when a resource pack mentions custom entity models or animations.
ETF stores its settings in a file inside the config folder of your Minecraft directory. Deleting that file resets every option to its default the next time you launch, which is a quick fix when a changed setting causes odd behaviour. Back it up first if you have customised several options.
OptiFine offers similar texture features as an all-in-one install but does not run on Fabric or NeoForge. For other texture types, CIT Resewn handles custom item textures and Continuity adds connected textures. These complement ETF rather than replace it. See our alternatives page for a full comparison.

Pick the right file, install Fabric Loader, and confirm ETF is running before you add a single resource pack.
ETF changes what mobs look like on the surface. EMF changes their shape. Here is when you need one, the other, or both.
Give every cow, villager or wolf its own look using a single .properties file. Copy-ready examples included.
Add an _e layer and ETF renders it at full brightness, so eyes and markings glow even in total darkness.
Short answer: no. ETF is a Java Edition mod. Here is what Bedrock players can do instead, and which 'Bedrock ETF' files to avoid.
Both setups render the same resource packs. The difference is loader support, performance and how they fit with other mods.
