Custom Player & Entity Models (KAIMyEntity-Reborn)
Minecraft has always been a canvas for creativity, but your character is usually stuck in the same blocky shape. Custom Player & Entity Models (KAIMyEntity-Reborn) shatters that limitation by letting you swap default entity and player models for detailed MMD characters. If you have ever wanted your avatar to move with the fluid grace of a Vocaloid or an anime heroine, this mod is your gateway.
What Does This Mod Actually Do?
At its core, Custom Player & Entity Models (KAIMyEntity-Reborn) is a maintained revival of the original KAIMyEntity project by kjkjkaistudio. It allows you to replace the standard Minecraft player model with external MMD files in .pmx or .pmd format. Beyond simply looking different, the mod injects a full animation system driven by .vmd files. Your character will walk, sprint, sneak, swim, jump, ride, and even swing a sword with bespoke motions rather than the stiff vanilla rig.
This is not a simple texture pack. It is a deep model replacement framework that reads your custom assets from a dedicated folder structure. The mod also supports multiple skins per character, letting you cycle through up to five variants of the same model on the fly.
Supported Versions and Loaders
Before you rush into installing, you need to know the technical boundaries. Custom Player & Entity Models (KAIMyEntity-Reborn) is built specifically for Minecraft 1.16.5 and runs exclusively on Windows x64 systems. It is a Forge mod, so your game profile must be running the Forge loader for that version. There is no Fabric support, and the mod will not function on macOS or Linux. The developer has noted that a 1.19.2 revival is possible but not guaranteed, so for now 1.16.5 is the definitive home for this tool.
A Critical Installation Note
This mod is unusual because it requires two separate files working in tandem. You must place the main .jar file and the KAIMyEntity_Saba.dll file side by side in your mods folder. If the DLL is missing, Minecraft will crash on startup. If you are certain the DLL is present but the game still crashes, install the Microsoft Visual C++ 2015 Redistributable x64 package. Servers only need the .jar file, but clients need both.
How to Install Custom Player & Entity Models (KAIMyEntity-Reborn)
Getting started is straightforward once you understand the folder layout. Here is the step-by-step process:
- Ensure you are running Minecraft 1.16.5 with Forge installed.
- Download Custom Player & Entity Models (KAIMyEntity-Reborn) and locate both the .jar and the KAIMyEntity_Saba.dll files.
- Drop both files into your mods folder.
- Launch the game once to generate the necessary directories, then close it.
- In your Minecraft data folder, create a folder named KAIMyEntity.
- Inside that, create an EntityPlayer folder for single-player models and an EntityPlayer_Username folder for multiplayer, replacing Username with your actual Minecraft name.
- Create an Animations folder with a mandatory default subfolder for fallback animations.
- Place your .pmx or .pmd model files inside the EntityPlayer folders and your .vmd animation files inside the Animations folders.
For those who prefer a smoother setup, the foxygame.net launcher offers a one-click install option that handles the file placement for Custom Player & Entity Models (KAIMyEntity-Reborn) automatically, saving you from manually juggling the DLL and JAR files.
Organizing Models and Animations
The folder structure is flexible but strict. Inside EntityPlayer, you can create subfolders for each character. The mod looks for model0.pmx as the base, then model1 through model4 for additional skins. Press numpad 2 to cycle models and numpad 3 to switch skins. For animations, the default folder holds shared motions, while character-specific folders override them. This means you can give one character a unique sword swing while everyone else uses the standard animation.
Animation Support and Gameplay Impact
The animation list is impressive for a niche mod. Supported .vmd files include walk, sprint, sneak, swim, jump, idle, swingLeft, swingRight, onLadder, ride, ridden, and sleep. Recent updates added flying_loop and flying_idle for more natural aerial movement, plus a dedicated jump.vmd and swingSwordRight.vmd. The swim animation now only triggers when you are actually swimming, not merely wading into water.
This level of detail transforms multiplayer servers into vibrant stages where every player can look and move like a unique character. Roleplay communities, anime fan servers, and content creators will find the most value here.
Final Thoughts
Custom Player & Entity Models (KAIMyEntity-Reborn) is a passion project that fills a very specific niche. It is not plug-and-play for everyone, especially if you are unfamiliar with MMD assets or Windows troubleshooting. However, for those willing to invest the time, the payoff is a Minecraft experience where your character truly feels like your own. Just remember the golden rule: JAR and DLL together, always.
