Trimmed down fork of the UnityMeshSimplifier Library adapted for modern non-Unity .NET 9+ projects

Install the NuGet package Sowa705.MeshSimplifier

using MeshSimplifier;

// load your 3D model into a Mesh object
Mesh mesh = new Mesh();
mesh.vertices = ...;
mesh.triangles = ...;
mesh.submeshes = [new SubMesh(0,mesh.triangles.Length)];

MeshSimplifier simplifier = new MeshSimplifier();

simplifier.Initialize(mesh);
simplifier.SimplifyMesh(0.5f);

var optimizedMesh = simplifier.ToMesh();

• Unity integration
• BlendShapes
• BoneWeights (may be re-added in the future)
• 3D and 4D UVs (may be re-added in the future)
