UnityMeshImporter

Runtime mesh importer for Unity using AssimpNet. This mesh importer creates UnityEngine.GameObject from mesh files.

Update: Tested on Linux, macOS and Windows.

What is Assimp?

Open Asset Import Library (Assimp) is a cross-platform 3D model import library which aims to provide a common application programming interface (API) for different 3D asset file formats. Written in C++, it offers interfaces for both C and C++. Bindings to other languages (e.g., BlitzMax, C#, Python) are developed as part of the project or are available elsewhere.

Quickstart

Before you start, you may need to install minizip package by

$ sudo apt install minizip

Install "com.donghok.meshimporter" package as follows: In the Packages directory of your Unity project,
```
$ git clone https://github.com/eastskykang/UnityMeshImporter.git com.donghok.meshimporter
```
or

Open Packages/manifest.json and add "com.donghok.meshimporter":"https://github.com/eastskykang/UnityMeshImporter.git" to the "dependencies" list.

As the package is imported, you can use UnityMeshImporter as follows:

using UnityMeshImporter;

string meshFile = <YOUR-MESH-FILE-PATH>;
var ob = MeshImporter.Load(meshFile);

The mesh importer uses Unity "Standard" shader. Please add Standard shader to Project Settings > Graphics > Built-in Shader Settings > Always Included Shaders.
