Unreal Frame Debugger is an Editor code plugin for capturing an Unreal Engine

Render Dependency Graph frame and inspecting its render passes, shader

parameters, textures, and buffers.

Supports Unreal Engine 5.7 and 5.8 on Win64, including standard Epic Games

Launcher installations. Install the optional Engine Source component before

using the plugin.

This plugin uses version-specific Renderer private headers and RDG debug

metadata to provide full pass enumeration. No engine modification or engine

rebuild is required. Install the package matching your exact Unreal Engine

minor version.
