Method 1: Using a Unity Plugin to Import Directly

Step 1: Install the MMD4Mecanim (Beta) Plugin

Plugin Site: Stereoarts Homepage (Per the author’s request, do not upload this to GitHub)
Direct Link: MMD4Mecanim_Beta_20200105.zip

Step 2: Open Unity and double-click the MMD4Mecanim.unitypackage file in the downloaded package.

Step 3: Import all MMD model files into Unity

Select the auto-generated .MMD4Mecanim file and click “Agree” (you can add animations, music, etc., here).

The advantage of this method is that it maximizes the original MMD rendering style without requiring manual shader setup or external software.

Method 2: Convert MMD to FBX via Blender Plugin

Step 1: Install the Blender Plugin

GitHub: cats-blender-plugin

This plugin allows Blender to recognize MMD .pmx files. You can then export to formats like .fbx or .stl (Unity prefers .fbx).

Step 2: Import the exported FBX and all original textures into Unity

The rendering style might look different upon import, so you’ll need to configure shaders manually.
Setting up your own shaders allows you to unify the art style across different models in Unity. For a shortcut, you can download a model with the desired style from the Unity Asset Store and apply its shader to your MMD model. (Animations are compatible, and colors can be tweaked manually).
