ETF Mod frequently asked questions

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.
