 ## Overview
 This is a plugin for the Unreal Engine to load 3D assets (e.g. FBX) at runtime. Made with UE5.4.2.
 
-## Prerequisites
-- Windows is the primary supported platform. macOS (arm64 only; x86_64 not supported) and Linux support is experimental.
-- Download and install [CMake](https://cmake.org/)
-  The check box "Add CMake to the PATH environment variable" that appears during installation must be checked.
+## Recommended approach: DynamicMesh (stable)
+
+**Use the `DynamicMesh` path for all builds.** The `ConstructDynamicMeshComponentFromAssetFile` and `ConstructDynamicMeshComponentFromMeshData` Blueprint functions are the stable, recommended methods that work correctly in both editor and packaged builds.
+
+> **StaticMesh functions are [Experimental].** `ConstructStaticMeshComponentFromAssetFile` and related StaticMesh functions have a known limitation in packaged builds (no editor): **materials display as a checkerboard pattern**. Avoid using them unless you understand and accept this limitation.
 
-> **Note:** The first build of the assimp library (a C++ dependency) takes approximately 5 or more minutes. Subsequent builds are fast. This is expected behavior.
+## Prerequisites
+- Windows (Win64) is the primary supported platform.

 ## Description of the technology inside
-We are using assimp as a git submodule, CMake is only needed to build assimp. The actual loading of the asset files is done by assimp, and this plugin only converts them from the format loaded by assimp to a format usable by the Unreal Engine. The build of assimp is done automatically during the project build process.
-
+We are using assimp for loading 3D asset files. Prebuilt Win64 binaries (`assimp-vc143-mt.dll` / `.lib`) are bundled under `Source/ThirdParty/assimp/Bin/Win64` and `Lib/Win64`. This plugin converts the data loaded by assimp into a format usable by Unreal Engine.
