MeshUtility.SetMeshCompression

Parameters

Description

Change the mesh compression setting for a mesh.

This allows you to enable mesh compression for meshes created from scripting, which have not been generated by the ModelImporter. That way you can generate compressed mesh assets from code.

using UnityEngine;
using UnityEditor;

public class ExampleMesh : MonoBehaviour
{
    void Start()
    {
        Mesh m = new Mesh();

        //Add mesh data here
        //m.vertices = your vertices;
        //m.triangles = your triangles;

        MeshUtility.SetMeshCompression(m, ModelImporterMeshCompression.High);
        AssetDatabase.CreateAsset(m, "Assets/CompressedMesh.asset");
        AssetDatabase.SaveAssets();
    }
}
