struct FShaderEntry uint64 Hash; // SHA-1 or MurmurHash of shader code + params uint32 Size; // bytecode length uint32 VendorMask; // e.g., 0x10DE (NVIDIA), 0x1002 (AMD) uint8 Bytecode[Size]; ;
Shader caches are highly specific to the exact version of the Unreal Engine the game is running, and sometimes even specific to the graphics card architecture. Copying and pasting a generic .bin file from a different game will rarely fix the issue; instead, it usually triggers a different "Fatal Error" crash. How to Fix the Error Safely (Step-by-Step)
