RHI Switcher for Blueprint is an Unreal Engine plugin that allows you to change the Render Hardware Interface (RHI) — such as DirectX 11, DirectX 12, or Vulkan — directly from Blueprints.

This plugin changes the RHI by updating the DefaultGraphicsRHI key in the WindowsTargetPlatform.WindowsTargetSettings section of DefaultEngine.ini using GConfig->SetString when SetDesiredRHI is called with an enum value (e.g., Vulkan).

• ✅ Switch between D3D11, D3D12, and Vulkan via Blueprints.
• ✅ Automatically updates the correct .ini configuration.
• ✅ Supports packaging for Shipping, Development, and Test builds.
• ✅ Minimal setup, no code required.
• ⚠️ Changes take effect after restarting the game/application (engine limitation).

2. Add the plugin to your project Plugins Folder.
3. Open your Blueprint and search for the node: Set Desired RHI.
