Seeking a C++ developer experienced with Unreal Engine 4.27.2 and DirectX to modify the engine's material system, enabling cooked materials to load and render correctly in the editor without upgrading to UE 5.3.
The project involves fixing a bug in Unreal Engine 4.27.2 that prevents cooked materials from loading properly in the editor, specifically for modding SDK purposes. The fix must maintain compatibility with existing UE 4.27.2-built games and avoid breaking legacy assets. The goal is to enable cooked materials (.uasset and .uexp) to load and render correctly in the UE 4.27.2 editor, despite the existing shader size mismatch error.
Tasks and Deliverables: - Analyze the UE 4.27.2 material system and shader deserialization process to identify the cause of the size mismatch error. - Develop a fix that allows loading of cooked materials into the UE 4.27.2 editor, ensuring they render properly without altering the core material graph, which is not recoverable from cooked assets. - Ensure the solution maintains backward compatibility with existing projects and assets built with unmodified UE 4.27.2. - Test the fix thoroughly to verify that cooked materials load, compile, and render correctly within the editor environment.
Required Experience: - Required: Proficiency in C++ programming, especially with Unreal Engine source code (version 4.27.2). - Required: Experience with DirectX 11 & 12, 3D graphics, and shader implementation within UE's C++ engine code. - Required: Deep understanding of Unreal Engine's material system, shader deserialization, and cooked content handling. - Nice to have: Background in engine source modification, shader compilation, and maintaining compatibility with legacy engine versions.
