I've found that Unity's job system doesn't perform as well as C#'s ThreadPool when stressed with thousands of small tasks so I recommend using C# APIs over Unity APIs whenever possible.<br> | I've found that Unity's job system doesn't perform as well as C#'s ThreadPool when stressed with thousands of small tasks so I recommend using C# APIs over Unity APIs whenever possible.<br> | ||

Much of Unity's API such as <code>new Mesh()</code> and <code>new Texture2D()</code> cannot be called from background threads. I suggest caching textures as <code>byte[]</code> or <code>Color32[]</code> which can then be loaded with [https://docs.unity3d.com/ScriptReference/Texture2D.LoadRawTextureData.html <code>Texture2D.LoadRawImageData()</code>]. Similarly, you can cache a Mesh by caching a struct of vertices, triangles, normals, and tangents. | Much of Unity's API for GPU assets such as <code>new Mesh()</code> and <code>new Texture2D()</code> cannot be called from background threads. | ||
