AssetRipper vs UE Viewer

AssetRipper is an analysis tool for game developers working with Unity game files. It can identify accidentally included dependency assets, broken asset references, and code that could not be inlined or trimmed, as well as convert assets to native Unity format. Unity Project Export creates a project that can be opened in Unity Editor. For viewing content outside Unity, Primary Content Export produces meshes, scenes, and prefabs as GLB models, including for Blender workflows. Supported Unity versions range from 3.5.0 to 6000.4.X, with support quality varying by version. Free stable and nightly builds are available for Linux, macOS, and Windows. Premium access costs $10 a month while an eligible membership is active, and includes features such as shader decompilation, static mesh separation, prefab outlining, asset path overrides, user-defined package export, and deduplication. Vulkan and OpenGL shaders can be decompiled on any platform, but DirectX shaders are limited to Windows. Traditional Il2Cpp analysis succeeds on about 10% to 20% of methods on x86 games, with lower success on other platforms.
